V letech 1988–1989 se jako stipendista Humboldtovy nadace na TU Clausthal věnoval problematice určování paleogradientu teploty ve vybraných sedimentárních pánvích. V období 1999–2011 se aktivně účastnil práce v komisi pro tepelný tok Mezinárodní unie geodetické a geofyzikální (IUGG), v letech 2003–2007 byl jejím tajemníkem. Předsedal Českému národnímu komitétu Mezinárodního programu geosféra-biosféra (2004 – 2009). V roce 2009 byl Akademickým sněmem AV ČR zvolen členem Akademické rady AV ČR a v letech 2013–2017 zastával funkci místopředsedy AV ČR pro I. oblast věd. Je autorem nebo spoluautorem více než 100 publikací z oboru geotermiky, dynamiky permafrostu a ložisek hydrátů metanu, rekonstrukce paleoklimatu a využívání geotermální energie.
