About Me

I am an Assistant Professor at the Department of Public Health, University of Copenhagen. I will be joining the research group led by Samir Bhatt and David Duchêne. I am also part of the Machine Learning and Global Health Network.

My research interests are in developing probabilistic machine learning and deep learning methods to understand complex patterns in social, environmental sciences and public health. Some particular topics that I am interested in are:

• Leveraging methods from deep learning to enhance the capabilities of classical probabilistic models. For instance, enabling popular models such as Gaussian processes to scale to high-dimensional datasets.
• Designing novel models and algorithms to leverage multimodal and multiresolution data sources. For instance, combining time series, satellite imagery, text and speech data to understand human behaviour and health outcomes.
• Phylogenetics, epidemiology, survey design, spatiotemporal modelling, Neural Processes, Gaussian Processes, Bayesian deep learning, approximate inference, sequential variational autoencoders, deep generative models,

Before joining the University of Copenhagen, I first obtained my integrated masters’ (MSci; 2015-2019) in Mathematics from Imperial College London, during which I was an exchange student at École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland for an academic year. I then obtained my PhD (2019-2023) from Imperial College London, as part of the EPSRC Centre of Doctoral Training in Modern Statistics and Statistical Machine Learning at Imperial and Oxford. I had the privilege of being supervised by Seth Flaxman and Yingzhen Li. I was also a member of the Imperial College London COVID-19 Response Team during the COVID-19 pandemic. After my PhD and between 2023-2024, I worked as a Research Scientist for a year at Fano, where I worked on automatic speech recognition.
