I am a Bonn Junior Fellow with the Hausdorff Center for Mathematics at Rheinische Friedrich-Wilhelms-Universität Bonn,Germany. From 2017 to 2020, I was a Von Karman Postdoctoral Instructor in Applied and Computational Mathematics at the Department of Computing and Mathematical Sciences, California Institute of Technology (Caltech) in Pasadena, USA.
In July 2017, I completed my PhD at the Cambridge Centre for Analysis (CCA) Doctoral Training Centre, University of Cambridge and Imperial College London, under the supervision of Prof. José A. Carrillo and Prof. Clément Mouhot. A copy of my thesis can be downloaded here. I’m honoured to have received the 2016 Imperial College Outstanding Student Achievement Award.

My research interests lie at the interface of model-driven and data-driven approaches.
Mathematical Tools for PDE Analysis: This part of my research focuses on partial differential equations and their applications. My current interests are among others non-linear drift-diffusion equations, kinetic theory, many particle systems, gradient flows, entropy methods, optimal transport, functional inequalities, parabolic and hyperbolic scaling techniques, hypocoercivity and diffusive models in mathematical biology.
- Mathematical Tools for Data Analysis: I am interested in developing rigorous mathematical tools for data analysis in the context of inverse problems, Bayesian inference and machine learning, unsupervised and semi-supervised learning, focusing on data clustering and classification, graph Laplacians and their continuum counterparts, spectral analysis, uncertainty quantification and consistency analysis.
I believe that it is not just about what mathematical analysis can do for applications, but also what applications can do for mathematics. Applications that benefit from a PDE approach often generate new questions giving rise to novel mathematical theories, and thus providing insights not just for the application at hand, but also enabling to push boundaries in seemingly unrelated fields. I am interested in how PDE techniques can be employed to answer modeling questions across different scales, disciplines and applications. For more details about my research, have a look here.
- Our Fundraising Campaign to support virtual math education programs in Africa is now LIVE! We are coordinating efforts across Africa and internationally to create a virtual maths camp experience (http://virtualmathscamp.com), a collection of events and resources accessible across different countries, platforms and delivery mechanisms with the potential to have long lasting impact. We want to turn the challenges presented by the current pandemic into an opportunity, and continue to provide a math camp experience for students, teachers, and facilitators from across the globe – in a new, dynamic, partially virtual and fully international environment.
- Our paper “Consistency of semi-supervised learning algorithms on graphs: Probit and one-hot methods” has been accepted for publication in the Journal of Machine Learning Research.
- Updated version of our pre-print “Spectral Analysis Of Weighted Laplacians Arising In Data Clustering” is now up on arXiv.
- Our CIMPA school “Partial Differential Equations (PDEs) and Calculus of Variations” is now online here! It will take place at the Institut de Mathématiques et de Sciences Physiques (IMSP) in Dangbo, Benin, 30 August – 10 September, 2021. For more information on the school and how to register, check out the website.
- Our school “Mathematical Methods in Analysis and Probability” (AMS-African Mathematical School), originally scheduled to take place at the African Institute of Mathematical Sciences (AIMS) Ghana 17-28 August 2020, had to be postponed to 2021 due to the SARS-CoV-2 outbreak. New date TBC.
- I accepted a position as Bonn Junior Fellow at Rheinische Friedrich-Wilhelms-Universität Bonn(Germany) starting in September 2020.
- I accepted a junior faculty position in the Department of Computing and Mathematical Sciences (CMS) at California Institute of Technology (US), starting in Fall 2022.
- Together with Marie-Therese Wolfram, I’m co-organizing a minisymposium on “Mean-field models for large interacting agent systems” at the SIAM PD 2019 conference.
- I’m organizing the workshop “Cross-Pollination in Mathematics Education” at the African Institute of Mathematical Sciences in Biriwa, Ghana, 29 April – 3 May 2019.
- I’m organizing this year’s Southern California Applied Mathematics Symposium at Caltech, US, 27th April 2019.
- As part of the special topics course on Optimal Transport that I’m teaching in Winter term 2019, I’m organizing a special seminar series on Optimal Transport.
- Together with Bamdad Hosseini, I’m co-organizing a minisymposium on “Inverse Problems in Machine Learning” (Part 1 & Part 2) at the SIAM CSE 2019 conference.
