Agu Laisk (born 3 May 1938) is an Estonian plant physiologist and physicist. He is a professor emeritus at the University of Tartu and a member of the Estonian Academy of Sciences (elected 1994).[7][8]

His research has focused on the physiology and biophysics of photosynthesis and photorespiration, including gas-exchange measurement approaches and mathematical modelling of leaf CO2 exchange.[8][9]

Education and early career

Laisk studied physics at the University of Tartu, graduating in 1961.[7] He earned a Soviet-era Candidate of Sciences degree (physics and mathematics) in 1965 and a Doctor of Sciences degree in biology in 1975, with research on the kinetics of leaf photosynthesis and photorespiration.[7][4]

Academic career

From the 1960s to the early 1990s, Laisk worked in research institutes of the Estonian Academy of Sciences, where he led work linking plant-canopy radiation physics with physiological interpretation of photosynthesis.[8][4] From 1992 he worked at the University of Tartu (Institute of Molecular and Cell Biology), becoming professor and heading plant physiology, and later serving as senior researcher and professor emeritus.[8][7][4]

He has held visiting research positions at several universities and research institutes, including the Australian National University and other European and U.S. institutions, as documented in institutional CV material.[4]

Research

Laisk’s work addresses quantitative limitations and regulation of photosynthetic CO2 assimilation in C3 plants, including the interaction between photosynthesis and photorespiration and the interpretation of gas-exchange signals under varying light and CO2 conditions.[8][9]

Laisk method

In plant ecophysiology, the term Laisk method commonly refers to a gas-exchange procedure based on measuring net CO2 assimilation at low intercellular CO2 (A/Ci) across multiple irradiances and using the intersection properties of these relationships to estimate respiration in the light (and related CO2-exchange parameters used in modelling).[1][2][3] The method is widely discussed and compared with alternative approaches in the peer-reviewed literature, including assessments of assumptions and applicability across conditions.[10]

Awards and honours

  • 1994: elected member of the Estonian Academy of Sciences.[7]
  • 1999: Estonian national research award (chemistry and molecular biology), shared with Vello Oja.[5]
  • 2001: Order of the White Star, 4th Class.[4]
  • 2007: Estonian Academy of Sciences medal (recipient list includes Laisk).[11]
  • 2013: University of Tartu Grand Medal (recipient list includes Laisk).[12]
  • 2018: Estonian national research award (lifetime achievement).[6][9]
