Doctoral Finishing Fellowship – Summer 2023 Recipient – Thusitha Divisekara

I completed my bachelor’s and master’s degrees at the University of Peradeniya in Sri Lanka. In the fall of 2018, I started my PhD in chemistry at Michigan Tech and joined the research group of Dr. Lynn Mazzoleni. The group’s primary research focuses on using ultrahigh-resolution mass spectrometry to study the chemistry of organic aerosols in the atmosphere.

In my research, I have developed a new post-data processing approach for liquid chromatographic high-resolution mass spectrometric data. The need for this approach arose from the requirement to effectively analyze complex mixtures in the environment. Mimicking ambient BBOA is one of the significant challenges scientists face in atmospheric research. Therefore, I improved liquid smoke to simulate the ambient BBOA by mixing them with different environmental species. This significantly impacts aerosol research as it provides an option for environmentally relevant lab studies.

I would like to thank my advisor Dr. Lynn Mazzoleni for her guidance, support, and encouragement during my research journey. Her mentorship has been invaluable to me and has played an integral role in helping me with my accomplishment. Also, I sincerely thank the Graduate Dean Awards Advisory Panel for selecting me as a recipient of the finishing fellowship, which will allow me to focus on finishing my dissertation and publishing my work.
