Lutz Warnke
I am an Associate Professor of Mathematics at UC San Diego.
I am particularly interested in random graphs and processes, phase transitions, and combinatorial probability (as well as applications thereof to extremal combinatorics, Ramsey theory, and related areas).
I am looking for highly motivated PhD students and postdocs.
I completed my PhD at the University of Oxford in 2012 under the supervision of Oliver Riordan.
Afterwards I was a elected junior research fellow at Peterhouse College, University of Cambridge.
I subsequently received tenure at Georgia Institute of Technology.
I received in 2014 the RichardRadoPrize (German Mathematical Society),
in 2016 the Dénes König Prize (SIAM),
in 2018 a Sloan Research Fellowship,
and in 2020 a NSF CAREER award.
