Sarojini J.K.A. Ubhayasekera

Dr. Ubhayasekera received her M.Sc. in Food Chemistry at the Department of Food Science, Swedish University of Agricultural Sciences, Uppsala, Sweden on 2004, and her Ph.D. in Food Science in 2010 from the same University. The PhD thesis title is: ‘Sterols and Oxysterols: occurrence and analysis in by-product feed fats and animal tissues’ (On-line publication: diss-epsilon.slu.se:8080/archive/00002066/). Dr. Ubhayasekera has been working extensively on oxysterols in fats and oils and in food lipids.
