About me

I am a Postdoctoral Scholar, working with Dr Nina Miolane at Geometric Intelligence Lab, University of California, Santa Barbara, USA. Previously, I worked with Prof Matthew J. Clarkson at WEISS (Wellcome / EPSRC Centre for Interventional and Surgical Sciences), University College London (UCL), UK. Before that, I worked with Prof Adrien Bartoli at EnCoV, Université Clermont Auvergne, France. I obtained a PhD in Computer Science supervised by Prof Niloy J. Mitra at Smart Geometry Processing Group, UCL.

Research interests

I utilise geometric/deep learning to discover the dynamics of protein shape changes (conformational changes) from cryo-EM images. In this context, I also develop models that are biophysically grounded and more interpretable while not sacrificing their accuracy.
