We are looking for summer trainees with an interest in theoretical astrophysics and/or theoretical physics. In addition to theoretical work, our projects include a significant computational aspect. We encourage students interested in theory and computation to join the Theoretical Extragalactic astrophysics research group for a three-month period over the summer.
This year, the projects on offer are related to the KETJU-project, which has recently received funding from both the European Research Council and the Academy of Finland. In this project the aim is to use the newly developed simulation code KETJU to model the dynamics of supermassive black holes in galaxy simulations. Using KETJU the large-scale structure of galaxies can be studied, while simultaneously resolving accurately, the small-scale dynamics close to the supermassive black holes.
1) Modelling the cosmological formation of cored early-type galaxies:
In this project the goal is to use numerical cosmological simulations to study the effect of binary supermassive black holes (SMBHs) on the central structure of massive elliptical galaxies. The interaction between the SMBH and the surrounding stars tend to eject stars from the centre of the galaxy and using KETJU this process can be studied in detail. However, gas cooling and central star formation contributes to increasing the central stellar density. In this project the aim is to study what is the dominant process for setting the central stellar density in massive galaxies. Good computing skills and knowledge of galaxy formation theory and galactic dynamics are advantageous for this project.
2) Gravitational wave kicks from merging supermassive black holes:
In the final stages of the merger of a supermassive black hole (SMBH) binary copious amounts of gravitational waves will be emitted. In addition, the merged SMBHs will receive a kick that depends on the orbital orientation, masses and spins of the individual SMBHs prior to the merger. Using the Post-Newtonian formalism in KETJU the gravitational wave energy spectrum as a function of frequency and the amplitude and direction of this kick can be calculated. In this project the aim is to study the dynamics of merged SMBHs in the centres of massive galaxies. Good computing skills and prior knowledge of general relativity and galactic dynamics are advantageous for this project.
3) Black hole accretion and feedback in merging galaxies
Supermassive black holes (SMBH) at the centre of massive galaxies accrete gas, thus converting efficiently the potential and kinetic energy of this gas into radiation, which heats the surrounding gas and affects the evolution of the entire galaxy. This interplay between gas and SMBHs is termed the black hole accretion and feedback process, and it is a key ingredient in modern galaxy formation models. In this project the goal is to use KETJU numerical simulations to study how the accretion and feedback process of binary SMBHs affects the properties of merging galaxies. Good computing skills and knowledge of galaxy formation theory are advantageous for this project.
4) The impact of astrophysical processes on the structural properties of forming galaxies
In this project the aim is to use outputs from cosmological KETJU simulations to study the impact of astrophysical processes on the internal structure and kinematics of forming galaxies. In particular, this project aims at understanding how galaxy mergers and black hole feedback processes can give rise to counter-rotating stellar components. In addition, different star formation quenching mechanisms (environmental, morphological, energetic) will be studied, with a focus on understanding what imprints will be left on the spatial distribution of the stars. Finally, we will also study the formation and evolution of nuclear stellar components around supermassive black holes. Good computing skills and knowledge of galaxy formation theory are advantageous for this project.
When applying please indicate your preference for the research topic. All research topics could also form the basis for either a Bachelor or a Master thesis in Astrophysics, Theoretical physics or a related field.

The Earth’s radiation belts are the site of acceleration for electrons reaching velocities comparable to the speed of light. Generation of relativistic electrons constitute a threat to satellites and an open fundamental problem for a wide range of astrophysical plasmas in which particles are confined by large-scale inhomogeneous fields. One of the two dominant frameworks to quantify particles' acceleration, radial diffusion, relies on qualitative arguments that violate basic conservation laws, such as the conservation of particles. In this project, we will remedy the shortcomings of radial diffusion by building a more systematic algorithm for calculating diffusion coefficients. The process to achieve this, consists in solving kinetic problems with scale separation — a useful skill from the toolbox of theoretical physics.
The project is suitable for a BSc and MSc thesis.

The goal of this project is to learn about and perform calculations in holographic duality. This duality is a discovery in theoretical physics (more specifically in string theory) that relates two very different types of theories; a gravitational theory and a quantum field theory. Results in one theory can be translated to results in the other.
This duality can be used as a tool to explore many different areas of physics. Researchers including several here in Helsinki are using it to study nuclear physics, condensed matter physics, and more.
We are searching for 1-2 summer trainees interested in learning about holographic duality as well as other areas of theoretical physics and in gaining some experience in performing related calculations. The details of the project are somewhat flexible and will be chosen considering the experience and interests of the trainee.

The computational field theory research group is searching for summer trainees interested in particle physics and/or cosmology, and preferably also in computational methods. The positions are for 3 months, with exact dates to be agreed upon.
Our research topics include gravitational wave production in exotic particle physics processes in the very early Universe. The produced gravitational waves may be observable with the European Space Agency's LISA gravitational wave mission, scheduled for launch in the next decade. This yields a unique window to the early Universe and to the particle physics processes which can produce gravitational waves.
The summer trainee research projects are chosen according to the experience and preference of the trainees. The research projects can form the basis for either a Bachelor or a Master thesis.

Uranium electronic structure in UxOy compounds by L-edges X-ray emission spectroscopy
The attractiveness of uranium compounds is not only due to their high relevance on safety and economic performance of the nuclear power plant or the sustainability of the nuclear waste management but also from a fundamental point of view. Indeed, such materials show exciting interdependence between their properties and their complex electronic structure. Over the last decade, systematic studies of the relationship between electronic structure and ground state properties were conducted on metallic compounds providing opportunities to develop more accurate and predictive theoretical model in 5f electron physico-chemistry. However, the case of oxide UxOy compounds remains unclear.
Recently, X-ray emission spectroscopy (XES) revealed itself to have the potential to provide detailed information and quantification of 5f delocalization. However, almost nothing is known about XES on uranium compounds, essentially because of the lack of the corresponding data, such a technique being only in its infancy at synchrotron radiations facilities. The renewal of laboratory XES instruments with performance complementing the synchrotrons is providing the opportunity to fill this gap directly at laboratory.
Within the XTREME project (Helsinki Institute of Physics), this summer position aims to perform extensive and systematic XES experiments on uranium oxide samples and to interpret the resulting data based on state of the art electronic structure calculations.

The genome of an oragnism can be investigated with DNA sequencing. DNA sequencing breaks the genome into small fragments and reports the nucleotide sequence of these fragments, i.e. substrings of the genome. We develop data structures and algorithms for analysing this kind of sequencing data. Possible topics for the summer internship include (i) lossy compression of sequencing data and (ii) indexing discriminating substrings of genomic data. The actual topic will be tailored according to the interests of the chosen applicant.
Programming skills and knowledge of algorithms and data structures is needed. Knowledge of biology or bioinformatics is beneficial but not necessary. The topics in this project are suitable for Master's thesis work.
The positions are part of the “Multidisciplinary Center of Excellence in Antimicrobial Resistance Research” which is one of the units selected by the Academy of Finland in Finnish Centers of Excellence in Research 2022-2029 call. We will use various data analysis methods, e.g., evolutionary theory based inference, machine learning, symbolic regression, reinforcement learning, to study how antimicrobial resistance develops. This theme is at the interface of microbial evolution and AI-driven data science.
There are several approaches for automating the design of deep neural networks (DNNs) in recent years. The main idea of this work is to automatically design new deep neural architectures and tune their associated hyperparameters. Exact optimization approaches cannot easily be used for such a NP-complete optimization problem. A wide variety of related works using specific heuristics, metaheuristics, and reinforcement learning have been proposed to confront with the problem. However, these works have lots of troubles due to the computationally expensive of training DNNs. It is necessary to have optimal parallel solutions for DNNs training process.
In this work, the student will have chance to study how to parallelize the DNN training algorithms. In addition, students will do empirical evaluations of the parallel algorithms on supercomputers. As a result, the student can identify the advantage and disadvantage of developing a general optimal parallel algorithm which paves the way for further research in parallelizing programs. The real-world applications can be considered are Natural language processing, Computer Vision, etc. The project can potentially be extended to either a Bachelor's or Master's Thesis project.
The Multi-Source Probabilistic Inference group works on statistical machine learning and artificial intelligence. We are looking for excellent candidates interested in fundamental research on approximate Bayesian inference (variational approximation, Hamiltonian Monte Carlo) or data-efficient learning (domain adaptation, data-efficient reinforcement learning, data integration). You can also suggest your own topic that relates to our main research themes.
We expect you to have completed some advanced courses in machine learning (e.g., Bayesian Machine Learning or Advanced Course in Machine Learning) or statistics (e.g., Computational Statistic, Advanced Bayesian Inference) and to have strong interest in pursuing doctoral studies. Both computer science and statistics students are encouraged to apply, and the topic is suitable as a MSc thesis.
Colored de Bruijn graphs are a space-efficient model for reference sequence databases in bioinformatics. In this project, you will work on improving and extending our existing colored de Bruijn graph tool Themisto (https://github.com/algbio/themisto). This project is ideal for a student who is familiar with the C++ programming language and has an interest in algorithmic bioinformatics. The project can be extended to a master's thesis.
The Constraint Reasoning and Optimization Group has summer intern openings for summer 2022. Interns will engage in forefront research guided by senior researchers in the group. Topics include automated reasoning and optimization techniques for NP-hard real-world problems (ranging from theoretical analysis to practical algorithm development, implementation, and empirical studies); and symbolic techniques for formally verified and explainable AI. For successful internships, the work done during the summer may be extended into an MSc thesis.
Differentially private machine learning studies learning methods that can operate while guaranteeing privacy of the data subjects. We apply differential privacy in the context of various modern machine learning methods, including Bayesian methods, deep learning and federated learning. Depending on your background, the work will combine working on the mathematical theory of differential privacy, general methods development, implementation and application of the developed methods in different applications. The topic is suitable for a Master's thesis topic.
The main focus of the project is on the use of GPU computing to accelerate Big Data processing using the Apache Spark distributed computing framework. The job can be also alternatively be extended to a Master's thesis position on the topic. The summer job is in the context of the Academy of Finland projects "Design and Verification Methods for Massively Parallel Distributed Systems (DeVeMaPa)" and "Massively Parallel Algorithms and Analysis for Metagenomics and Pangenomics (MAPAMEPA)". In the project we will develop methodology for the design and verification of massively parallel heterogeneous computing. We need new methods to support the massive increase in the amount of parallelism at all levels of the hardware/software stack. Such massive increases in parallelism will make some currently used programming paradigms infeasible and thus new methods need to be devised to cope with both Genomics and Industrial Big Data use cases.
Graph as ubiquitous models in many applications domains, including bioinformatics. In the Graph Algorithms Team of the wider Algorithmic Bioinformatics group, we can offer several topics involving graph algorithms, ranging from theory and experimental algorithmics to bioinformatics applications. See below our list of available projects, and mention in your motivation letter which projects interest you.
Most of the present deep learning models deal with real-valued data. In some applications, for example in signal processing and wireless communication domains the use of complex-valued data provides better results. Therefore, there is a need to design deep learning models to process the complex data. Therefore, we are looking for 1-2 summer trainees to
1) contribute in research group’s work in implementing a complex Long Short Term Memory (LSTM) network,
2) collect data using the department’s satellite navigation signal generator (Global Navigation Satellite Signal GNSS Orolia Simulator) and by collecting the live GNSS signal outdoors,
3 process the data and compare the performance results between conventional LSTM and Complex LSTM for detecting the anomalies in GNSS signals.
The task of the summer trainee is to help improve the home exercises and design an automated exam for the upcoming Autumn 2022 MOOC course on Big Data Platforms. The research group has already designed and run the course already twice and the main task of the trainee is to improve the used systems to allow for scalability to larger student volumes, create new home exercises, and to improve the scalability of the home exercises. The main requirements are good programming skills and interest in learning the latest Big Data Technologies with the help of the other members of the research group supervising the project.
The Sums of Products research group offers summer intern positions in 2022. We work on both theory and practice of exact and approximate algorithms for hard problems. The actual research tasks will be tailored for the intern based on their interests and skills, and may include research on the theory of algorithms, efficient implementation of algorithms, or heuristic algorithm designs evaluated mainly on empirically. Strong analytical skills are required. Examples of topics suitable for a Master's thesis are "Approximate counting of short paths: theory and practice" and "Selecting candidate parents for Bayesian learning of DAGs".
We have several topics in the fields of explainable AI (XAI), probabilistic AI, and building open-source tools.
(i) XAI for digital twins. We use machine learning algorithms together with physics simulators to model atmospheric transformations, measurement devices, and other processes. We call these models collectively "digital twins". In this project the task is to apply methods, developed, e.g., in our prior work to find useful and understandable explanations for the digital twins.
(ii) Uncertainty quantification for AI. In almost any real-world application of machine learning (atmospheric transformations included) concept drift is an issue, meaning that a model trained in some circumstances (e.g., under specific environment, for specific molecules etc.) may not work in other circumstances. The detection and quantification of concept drift is crucial: can we trust the outputs of our models?
(iii) Open-source tools for randomization and exploratory data analysis. Visual exploration of high-dimensional datasets and in the future of digital twins is a fundamental task in exploratory data analysis (EDA). We have developed a theoretical model for EDA, where patterns already identified and considered known by the user are input as knowledge to the exploration system. The user is shown views of the data where the user’s knowledge has been taken into account. In this project you will implement an open-source tool for exploratory data analysis. The tool should be web-based, cross-platform, and scale to large datasets. Programming skills and previous experience of open-source software development is considered an advantage.
We are looking for an intern to work in the intersection of ultrasound physics and computer science, to develop machine learning methods for physical phenomena. We collaborate with physicists working at Department of Physics on two related topics:
(a) Propagation of ultrasound waves in metallic systems carries information about their geometry and possible defects/contaminations. We develop machine learning models (e.g., deep learning, Bayesian optimisation, Gaussian processes) for both supervised and unsupervised learning problems in this context, using signals recorded by multiple IoT sensing devices.
(b) Ultrasound waves can also be used to levitate objects and create acoustic holograms in the air. We develop optimization algorithms to determine controlling parameters for a specific task (contactless sample handling, tactile display). Most of the work can be done on simulations and the results can be verified on the physical device.
The concrete task depends on your interest and background and is suitable also for a MSc thesis. An ideal candidate has completed a few machine learning courses (e.g. Bayesian Machine Learning, Deep Learning, or Advanced Course in Machine Learning) and is interested in signal processing and/or physics.
Quantum computing is an emerging technology that harnesses the laws of quantum mechanics to solve problems. In this project, the candidate will gain experience in programming with Qiskit to solve some computation tasks related to data management. The topic is suitable for a Master's thesis and we hope that the candidate can write a Master's thesis on this topic. Programming skills with Qiskit and knowledge of quantum algorithms are needed.
We are looking for multiple interns to work on tools and techniques for the efficient development and operation of machine learning systems (MLOps). To ensure that machine learning systems work for real, new ways are needed to ensure their correct and efficient operation as well as their smooth development and maintenance. In particular, continuous integration (CI/CD), testing, and life-cycle support of AI systems are the focus of our research projects. The work involves implementing research prototypes to try out ideas and performing measurements. We can flexibly tailor the work to match the applicant's profile. Applicants are expected to have good coding skills. Experience in machine learning and software engineering is useful.
The internship can be extended after summer as an MSc thesis worker or a part-time research assistant position.
The positions are related to the following European projects: Industrial Grade Machine Learning for Enterprises https://iml4e.org/ focuses on MLOps, Industrial-grade Verification and Validation of Evolving Systems https://ivves.eu/ focuses on testing of evolving systems, and VesselAI Horizon 2020 project https://vessel-ai.eu/ on enabling maritime digitalization by extreme-scale analytics, AI, and digital twins.
