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]
