The applicant will work in a multidisciplinary team involving both computer scientists and atmospheric scientists, with the thesis work containing publications in both domains. A successful applicant should have basic knowledge of ML and related mathematics. Knowledge of and interest in natural sciences is considered an advantage, but specific prior knowledge of atmospheric clustering processes is not required. We will consider students with background related to fields in computer or atmospheric sciences. We will also consider outstanding MSc students who wish to continue with PhD studies after graduation. The details of the project and supervision arrangements can be tailored depending on qualifications and preferences of the applicant.

The project is part of the Academy of Finland funded Finnish Center for Artificial Intelligence (FCAI) and Atmosphere and Climate Competence Center (ACCC) flagships.

Project 4: Bayesian workflow for iterative model building

Supervisor: Prof. Aki Vehtari (Department of Computer Science, Aalto University)

Statistical analysis is critical when it comes to obtaining insights from data. Despite the practical success of iterative Bayesian statistical model building, it has been criticized to violate pure Bayesian theory and that we may end up with a different model had the data come out differently. In this project, we formalize and develop theory and diagnostics for iterative Bayesian model building. We show that when the iterative model building is done carefully, the difference to the theoretically optimal result is negligible.

The practical diagnostics guide the modeller through the appropriate steps to ensure safe iterative model building, or indicate when the modeller is likely to be in the danger zone. By making applied scientific research and data analysis more reliable and reproducible, our understanding of the world and decision-making will be improved.

Project 5: Eco-evolutionary control theory and its applications to drug therapies 

Supervision: Prof. Ville Mustonen (University of Helsinki); This is a collaborative project with the Lässig Group at the University of Cologne.

Predictability and control of evolving populations is an emerging topic of high scientific interest and vast translational potential in applications such as vaccine and therapy design. This project will extend eco-evolutionary control theory to model free and multi-species contexts. For example, we will develop methods to find optimal control protocols for cell populations, find out what are the key determinants of controllability of a multi-species community, and apply the results to therapy optimisation. These projects are at the interface of microbial evolution, statistical physics, and information theory. A highly quantitative background and a burning interest in evolution are required.

Project 8. Open doctoral student position in Keijo Heljanko’s group – Massively parallel distributing computing with GPUs

Supervisor: Prof. Keijo Heljanko, Department of Computer Science, University of Helsinki and HiDATA Helsinki Centre for Data Science

The PhD Student position is in the context of the Academy of Finland project “Design and Verification Methods for Massively Parallel Distributed Systems (DeVeMaPa)”. The main focus of the project is on the use of GPU computing to accelerate Big Data processing and the theoretical foundations of these systems. Use cases include Bioinformatics applications and Big Data analytics.

The project 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 industrial Big Data use cases. These methods must also be accompanied with solid theoretical foundations, allowing for the development of automated testing and verification tools that are required to validate the parallelization runtime software before production deployment. A key challenge is the need for seamless integration of heterogeneous computing with GPUs and hardware accelerators (e.g., neural network accelerators), how can they all be handled in a unified Big Data programming framework?

Project 12: Deep generative modeling for precision medicine and future clinical trials

Supervisor: Prof. Harri Lähdesmäki (Department of Computer Science, Aalto University)

We are looking for a PhD student to develop probabilistic machine learning methods for heterogeneous health datasets from large-scale biobanks, clinical trials and single-cell experiments. This project develops novel deep generative modeling methods to (i) predict adverse drug effects using longitudinal/time-series data from large-scale clinical trials, and to (ii) harmonize large-scale health data sets for AI-assisted decision making to revolutionize future clinical trials.

Methodologically this project includes e.g. VAEs, GANs, Bayesian NNs, domain adaptation, and Gaussian processes. The work will be done in collaboration with research groups from the Finnish Center for Artificial Intelligence, and the novel methods will be tested using unique real-world data from our collaborators in university hospitals and big pharma company.

Project 13: Deep learning for continuous-time differential equation systems

Supervisor: Prof. Harri Lähdesmäki (Department of Computer Science, Aalto University)

Recent machine learning breakthroughs include black-box modeling methods for differential equations, such as Gaussian process ODEs [1] and neural ODEs. These methods can be viewed as “infinitely” deep learning methods where the traditional neural nets (implemented with a finite number of layers) are replaced with continuous-time differential equation system which, in turn, are parameterized by deep NNs, thus implementing deep learning methods that are effectively “infinitely” deep. These methods can be applied to standard classification and regression tasks but they are particularly useful to learn arbitrary continuous-time dynamics directly from data.

We are looking for a PhD student to join our current efforts in (i) developing efficient Bayesian methods for robust learning of infinitely deep models from data, (ii) developing neural ODEs to learn unknown/arbitrary dynamics of high-dimensional systems (e.g. in robotics, biology, physics or video applications) using a low-dimensional latent space representation, and (iii) further developing these methods for reinforcement learning.

Project 15: Probabilistic modelling for collaborative human-in-the-loop design

Supervisors: Prof. Vikas Garg, Prof. Samuel Kaski, PhD Markus Heinonen (Department of Computer Science, Aalto University)

We are looking for a doctoral student interested in developing probabilistic modelling and inference methods needed for complex design tasks, with drug design as a case study. The idea is to help experts steer the modelling system towards their design goals, while eliciting their prior knowledge to improve the models of the drugs. This is difficult because the goals may be tacit, uncertain and evolving. Another postdoc will develop the new molecular models for drugs, to which you are welcome to contribute. The work will augment and consolidate existing well-developed research pipelines of the supervisors. The selected student may also have the opportunity to work with and visit our collaborators at leading pharma companies and academic groups in Europe, USA, and Canada. This will be a transformative project, resulting in a virtual drug design laboratory.

Key methods we will need: probabilistic modelling and Bayesian inference, multi-agent modelling, sequential experimental design, POMDPs, reinforcement learning and inverse reinforcement learning. We expect applicants to master some of these, or be exceptionally eager and quick learners.

Project 16: Machine Learning for Health (ML4H)

Supervisor: Prof. Pekka Marttinen (Department of Computer Science, Aalto University)

Recent years have witnessed accumulation of massive amounts of health related data, enabling researchers to address a range questions such as: how to allocate healthcare resources fairly and efficiently, how to provide personalized guidance and treatment to users based on real-time data from wearable self-monitoring devices, or how to use genomic data to understand disease or antibiotic resistance. Central challenges in ML4H include integrating noisy data from multiple heterogeneous data sources, going beyond correlation to learn about causality, interpreting the models, and assessing the uncertainty of predictions, to name a few.

We tackle these by developing new models and algorithms which leverage modern machine learning principles: Bayesian neural networks, deep latent variable models, interactive machine learning, attention, reinforcement learning, and natural language processing. Examples of our ongoing interdisciplinary projects include: analysis of nationwide healthcare register data, mobile health, genomics, antibiotic resistance, and epidemiology. Successful applicants are expected to have an outstanding record in machine learning, statistics, applied mathematics, or a related field, and a passion to put these skills to use in interdisciplinary research to address some of the most burning challenges in today’s society.

Project 19: Data science for mental health and well-being

Supervisor: Dr. Talayeh Aledavood (Department of Computer Science, Aalto University)

People leave digital traces behind while interacting with different devices and online platforms such as smartphones, fitness trackers, and social media. These interactions with technology are producing large amounts of data of our daily activities. Studying these traces, we extract behavioral patterns to understand people’s behavior as well as the state of their health and well-being.

In the past 5 years in collaboration with clinicians we have run a study which has collected data from over 100 patients with mental disorders using devices such as participants’ smartphones and fitness trackers. The goal in this project is to continuously quantify the behavior and state of these patients using the collected data to find new behavioral markers for these disorders. We aim to predict the future state and mood of the patients. In other studies, we collect data from the general population, either in small scale (i.e. hundreds of people) from people’s personal devices (e.g. or from large number of people (up to millions) from social media platforms. The goal is to quantify behavioral patterns of users and changes in these patterns due to a disruption, e.g. the COVID-19 pandemic. 

The exact projects can be negotiated based on the interests and expertise of the student. In these projects we will use methods that are best fitting to each problem and will collaborate with other research teams with expertise in psychiatry, psychology, or experts in specific methods in statistical and machine learning. This position is especially suitable for an ambitious candidate who wants to work closely with their supervisor in a small research group and ideally has an academic career in mind. The supervisor is committed to the mentoring of junior scholars in their group in all aspects of their career, for example building an international network of collaborators with leading scientists.
