Dr. Dmitri Zaitsev

Associate Professor (Pure & Applied Mathematics)
18 WESTLAND ROW


Dmitri Zaitsev is an Associate Professor in the School of Mathematics, which he joined in 2003. He grew up in Kiev, Ukraine, where he won several Mathematics Olympiads, including All-Soviet-Union mathematical competitions. He studied Mathematics at Lomonosov Moscow State University and completed his Diploma in 1993 and his PhD, within 1 year from Diploma, in 1994 at Ruhr-University, Bochum, Germany.

Prior to joining Trinity College Dublin, he held researcher and visiting professor positions in Germany, France, Italy and the USA.

Dr Zaitsev's research comprises contributions to Geometry and Analysis of Several Complex Variables as well as connected areas of Mathematics, such as Lie Groups, Differential Geometry, Real and Complex Algebraic Geometry, Partial Differential Equations and Dynamical Systems.

He has over 20 international collaborators from over 10 countries and has authored over 60 peer-reviewed research articles. One of the conferences he co-founded and co-organised in Italy for many years, "CR Geometry and PDEs", became one of the major international conferences in the field.

In 2014, Dr Zaitsev founded a Trinity Campus Company, Personalotels Ltd, employing mathematical algorithms to help travellers finding hotels matching their personal preferences and avoiding the information overload problem.

Between 2013 and 2019, Dr Zaitsev served as School of Mathematics' Erasmus and Exchange Coordinator, during which period he expanded School's Erasmus agreements from 2 to 8, including 2 new countries, as well as negotiated one University-wide Memorandum of Understanding agreement - the first of this kind initiated by our School.

In 2018, Dr Zaitsev, being concerned with the numbers of academic journals using paywalls, co-founded Global Public Forum for scholarly publishing reform towards Fair Open Access and lead the campaign to collect signatures of support from many distinguished scientists.

In the same year, Dr Zaitsev co-founded Free Journal Network - an ecosystem of community-run high quality academic journals that are free for readers and authors.

Since 2019, Dr Zaitsev has been serving on TCD Open Scholarship Taskforce .

In April 2020 at the beginning of COVID-19 Pandemic, Dr Zaitsev entered as academic mentor multiple hackathons to fight against the virus, including the EUvsVirus hackathon hosted by European Commission, and currently advising over 10 projects among the winners, some of them being listed here.

To further help fighting coronavirus, Dr Zaitsev joined several global communities including the global CoronaWhy community and Just One Giant Lab" with Campaign for Open & Trustworthy Science.
