I am a tenure-track assistant professor at Auburn University. Prior to this role, I held a position as a visiting assistant professor at Emory University from 2019-2021, spanning four semesters. From 2018-2019, I was a tenure-track assistant professor at the University of Nevada, Las Vegas, for three semesters. Earlier in my career, I held the Black-Babcock visiting assistant professorship at the University of Kansas working closely with David Nualart and Yaozhong Hu, a role I fulfilled from 2015-2017 over the course of five semesters.
My academic journey began at the Swiss Federal Institute of Technology, Lausanne -- École Polytechnique Fédérale de Lausanne, where I obtained my Ph.D. in April 2013 under the supervision of Robert Dalang. Following this, I received an SNSF (Swiss National Science Foundation) post-doctoral research fellowship in 2014, which allowed me to spend a year at the University of Utah working with Davar Khoshnevisan.
My research focus lies within the fields of analysis and probability,
specifically working on stochastic analysis and stochastic partial differential
equations.
