Summer/Winter School: Digitise, Optimise, Visualise
We are organizing courses on convex optimisation taught this summer and next winter at USI Lugano. Recent educational methods will make it impossible not to understand the basic principles. The courses combine cutting edge theoretical knowledge with state-of-the-art visualisation techniques, and real-world data-intensive problems. Check it out at https://www.usi.ch/en/node/9755
Interests and Research
I am interested in finding structure in financial markets. My research focus is on methods to recover information that is not directly observable with the most innocuous assumptions possible. I try to learn every day about old and new techniques from engineering and mathematics, to keep myself informed about politics, and to enjoy and play music as much as possible.

JF2018 A template for preparing an accepted paper for publication in the Journal of Finance. Reuses parts of Richard Stanton's packages. Contains a main text as well as an internet appendix with examples of equations, figures, and references.
JFE2018 My paper 'An Anatomy of the Market Return' which was accepted by the copy editor of the Journal of Financial Economics. Contains a main text as well as an internet appendix. Note that the first submission to the copy editor must be made single page which you can achieve by commenting the first line and un-commenting the second line in the main document JFEmaintext.tex
DIconvex, with Liudmila Karagyaur. Ever worked with cross sections of options and wondering whether bid ask spreads admit at least one arbitrage-free path of option prices? Look no further. DIconvex maximizes the number of options you can keep such that at least one set of monotonic and convex prices exists within bid ask spreads. A mixed integer linear program does all the work. Fast, scalable and robust.
