Gert Schansker 博士
Gert Schansker博士畢業(yè)于荷蘭瓦赫寧根大學，獲得植物生理學和生物物理學博士學位。主要研究方向為光合機構的光脅迫反應，提出了光系統II受體側碳酸氫鹽的不可逆損失是光系統II活性降低的主要發(fā)生機制。他在研究中應用的主要非侵入性技術之一是葉綠素a熒光與光聲信號的同步測量技術。之后，在歐盟的資助下，前往希臘雅典Demokritos研究所從事博士后研究，使用EPR技術研究一氧化氮（NO）與光系統II錳簇S態(tài)的相互作用。他利用一系列單周轉飽和閃光及葉綠素熒光Fo信號與S態(tài)相關的周期-4振幅研究了S態(tài)與S態(tài)衰變對NO的響應，闡明了實驗中觀測到的NO誘導的多線態(tài)EPR信號可能就是S-2態(tài)的表征。他后來在瑞士日內瓦Reto Strasser博士的實驗室工作，研究了光暗轉換過程中820 nm吸收信號與葉綠素a熒光動力學之間的關系，系統研究了多種植物在各種脅迫條件下的快速葉綠素熒光誘導動力學曲線（O-I1-I2-P或O-J-I-P瞬變），為此類測量提供了幾乎完整的描述。在匈牙利結束了光適應和一種蝦青素過量導致煙草突變的研究之后，自2018年開始，Gert Schansker博士作為德國WALZ公司的應用科學家，負責Dual-KLAS-NIR和Multi-Color-PAM相關理論和應用的研究工作。
