Frank Jean-Marie Léon Pattyn is a Belgian glaciologist and professor at the Université libre de Bruxelles.^[1] He is best known for developing ice-sheet models and leading model intercomparisons.^[2]

Frank Pattyn was born in Etterbeek on 4 March 1966.^[3] He completed his Bachelor and Master degrees in geography at the Vrije Universiteit Brussel in 1986 and 1988, respectively.^[4] After a short period of military service in the Belgian Armed Forces,^[4] he then obtained his PhD from the same institution in 1998.^[5]

After completing his PhD, Pattyn then worked as a postdoctoral researcher at the National Institute of Polar Research, Tokyo, Japan (1999-2000) before coming back to Belgium as a research associate at the Vrije Universiteit Brussel.^[3]

In 2000, he started to teach geomorphology and climatology at the Université libre de Bruxelles where he became a professor in 2011. Since 2006, he has also become co-director of the Laboratoire de Glaciologie^[6] of the Université libre de Bruxelles.

He is currently Chairman of the Belgian National Committee on Antarctic Research,^[7] the Belgian branch of the Scientific Committee on Antarctic Research and the vice-president of the International Glaciological Society^[8] and Associate Chief Editor of Journal of Glaciology.^[9]

Pattyn has authored over 70 peer-review papers^[10] (including 6 from high-profile journals) covering various aspect of glaciology, which are cited over 1700 times.^[10]

His research includes ice-sheet modelling with in situ and remote sensing observations, to evaluate the present-day and future mass changes of the Antarctic ice sheet. He has developed several ice-sheet models, such as a three-dimensional thermomechanical ice-sheet model including higher-order stress gradients (Blatter-Pattyn model),^[11] and more recently the fast Elementary Thermomechanical Ice Sheet model (f.ETISh).^[12] Such models are capable of simulating the behaviour of fast-flowing ice streams and ice flow across subglacial lakes, and over long time scales.

He is also actively involved in a series of Ice-Sheet Model Intercomparison Projects (ISMIP),^[13] such as ISMIP-HOM, ISMIP-HEINO, MISMIP, MISMIP3D, and MISMIP+.

He took part in 19 expeditions to Antarctica and Arctic glaciers in order to study the interaction of glaciers and ice sheets with subglacial water and the ocean, using ground-penetrating radar and differential GPS.

Since taking office as a professor, he has also paid attention to the outreach of glaciology. In particular, he developed the Grantism model,^[14] which allows to simulate the evolution of the Greenland and the Antarctic according to parameters understandable to all (temperature, sea level). He recently set up the Tweeting ice shelf, a project which consists of two GPS placed on the Roi Baudouin Ice Shelf, East Antarctica that communicate their position and movement via Twitter.^[15]

Pattyn has received the 2018 Louis Agassiz Medal,^[16] an award^[17] from the European Geosciences Union that recognises his outstanding scientific contribution to the study of the cryosphere.
