Thesis-Thesis-Thesis: From PCB Metabolites Through PFOS to Reactions in Charged Droplets

The last two weeks have been going under the title “thesis-thesis-thesis” in our group. This spring one BSc student and two MSc students from our group have defended their thesis: Sara Khabazbashi, Helen Sepman, and Thomas Ledbetter. Both Sara and Thomas have dug into the analytical standard free quantification for pollutants. Sara specifically focussed on metabolites of […]

We are happy to introduce: Dr. Piia Liigand and Dr. Jaanus Liigand

Last week two of our PhD students, Piia Liigand and Jaanus Liigand, successfully defended their PhD theses. Both Piia and Jaanus worked intensively and successfully on understanding the ionization process in electrospray ionization source (ESI) and applying this knowledge for quantifying compounds with LC/ESI/MS without standard substances. Congratulations to the fresh doctors! Piia is continuing […]

Mari submitted her master’s thesis on reactions in charged droplets

Today our master’s student Mari Ojakivi submitted her thesis. She studied the reactions between 7 aldehydes and 4 nitrogen bases in charged droplets. For this, she built an in-house built electrospray system to generate the charged droplets. Mostly imines were observed as reaction products, but also amides were found in some reactions. For comparison, the same reactions […]

Defences in our group: Asko Laaniste and Hanno Evard

We are happily back from IMSC in Toronto and a very important celebration in our group has occurred! On the last day of August two PhD theses were defended in our group by Asko Laaniste and Hanno Evard. Asko wrote his thesis on ionization sources. Specifically focusing on the comparison of different sources for pesticides. […]
