About me

Since Decem­ber 2014, I am a PhD stu­dent in Com­pu­ter Sci­ence at the Chair for Lo­gic and Ver­i­fi­ca­tion.

I mainly work on the for­mal­i­sa­tion of pure math­e­mat­ics in Isa­belle/­HOL. I be­lieve that the form­al­isa­tion of a sig­ni­fic­ant por­tion of known math­em­at­ics is a feas­ible and worth­while en­deav­our.

My cur­rent work is the form­al­isa­tion of the (semi-)auto­mat­ic solv­ing and veri­fic­a­tion of cer­tain classes of math­em­at­ic­al prob­lems, par­tic­u­larly those of the asymp­tot­ics of real-val­ued func­tions.

Mathematical Interests

With vary­ing levels of pro­fi­ciency:

• Com­plex ana­lysis
• Dis­crete math­em­at­ics, com­plex­ity ana­lysis, ana­lytic com­bin­at­or­ics, ana­lytic number the­ory
• Ab­stract al­gebra and cat­egory the­ory
• So­cial choice the­ory
• De­cision pro­ced­ures
• Pro­gram­ming lan­guages, func­tional pro­gram­ming, type sys­tems, and pro­gramme veri­fic­a­tion

Current Work

• A Verified Solver for Linear Recurrences
• Analysis of Randomised Algorithms and Data Structures
• Semi-Automatic Real Asymptotics in Isabelle/HOL

Isabelle Formalisation Projects

See my separate list of formalisations projects.

Teaching

• Winter 17/18: co-or­gan­iser of the Func­tional Data Struc­tures Sem­inar and the practical course Spe­cific­a­tion and Veri­fic­a­tion
• Summer 16: co-or­gan­iser of the De­cision Pro­ced­ures sem­inar
• Winter 14/15: tu­to­rial (co-)su­per­vi­sor and proud Mas­ter of Com­pe­ti­tion (Jr) of In­tro­duc­tion to Func­tional Pro­gram­ming

Random stuff I made

• A small Haskell-based text snippet pasting service with Isa­belle high­light­ing
• A very small (∼250 LOC not counting GUI), on­line in­ter­ac­tive ray trac­ing demo in Java (with com­mented source code) that il­lus­trates the process of ray trac­ing. I made this when I was a BSc student and it fills me with nostalgia, so I leave it on here.
• Speaking of nostalgia: A raytracer in Java that I wrote as an en­try to a uni­ver­sity cod­ing con­test in my first semester. This won me a nice graph­ics card. ☺

Personal Interests

• Learn­ing lan­guages, lin­guist­ics, and phon­et­ics
• In par­tic­u­lar: learn­ing and speak­ing Es­per­anto (bon­volu kon­tak­ti min se vi vo­las pa­ro­li Es­pe­ran­ton kun mi)
• Bouldering and climbing
• Play­ing the ac­cor­dion and the low whistle
