Professor Tim Sparks

I received a Graduate Diploma in Statistics in 1986, an M.Sc (with distinction) in Applied Statistics in 1988, an M.Sc (with distinction) in Operational Research in 1993 and a Ph.D. in Environmental Sciences in 2001. After working in agricultural research I moved to ecological research at the Monks Wood Research Station in 1991 and stayed there until it was closed in 2009. I am currently a visiting professor at the Poznań University of Life Sciences and at the University of Liverpool, a visiting researcher in the Department of Zoology, University of Cambridge, and a Hans Fischer Senior Fellow, Technische Universität München. I have a wide range of interests associated with conservation, environmental change and the interpretation of data. I remain an advisor for the UK Phenology Network which I founded in 1998. I have co-authored more than 300 publications, particularly in phenology and climate impacts.
