 | Ivan Lerner University hospital assistant, HEGP | Email : ivan.lerner@inria.fr Office address: PariSanté Campus, 2 – 10 Rue d’Oradour-sur-Glane, 75015 Paris Webpage : Google Scholar page Bio: I followed a double curriculum in medicine & science at University of Paris driven by my curiosity for cognition and neuroscience. I did my master 2 in Cognitive neuroscience at ENS and several medical internships in neurology and psychiatry. I finally opted for a specialization in public health, because my interest evolved more towards the understanding and abstraction of learning principles, and their implementation in machines. Indeed, public health addresses medical questions at the population level, and I thought that machine learning would naturally be useful.During my public health residency, I conducted collaborative research projects in medical informatics (2 NLP publications: classifying clinical trials abstracts to be included in reviews, extracting clinical entities from medical records), biostatistics (oral presentation at ISCB: simulation study showing links between non-proportional hazards and composite endpoints in Cox regression) and epidemiology (under submission: prognosis value of troponin in population).To make sense of such diverse experiences, a unifying theoretical framework was needed, which I found in the theory of causality while attending a lecture by Peters.I have now started a part-time PhD on Machine Learning for Health (supervisors Francis Bach and Anita Burgun), where I am working on developing structure learning algorithms for electronic medical record data, which I believe is essential to achieve robust transfer learning. At the same time, I hold a position as a university hospital assistant at the Department of Medical Informatics of the Hôpital Européen Georges Pompidou, where I bring my expertise to local research projects, and I teach medical students at the University of Paris. |
