Despite the importance of these aerosol particles\, they remain poorly understood and constitute the largest degree of uncertainty in climate models. Recent studies have also led to the development of a novel biosphere–atmosphere feedback loop hypothesis whereby plants may be altering the emission of biogenic terpenes to enhance rainfall during drought conditions. This lecture will describe efforts within my lab towards the synthesis of putative biogenic terpene-derived constituents of atmospheric aerosol particles in order to confirm their identities and explore their climate relevant physical properties. Recent advances in the synthesis of isotopically-labeled pinene derivatives that are driving collaborative investigations into the complex oxidation pathways of terpenes in the atmosphere will also be presented along with ongoing efforts exploring the role of chirality in the atmosphere.\n\nRegan J. Thomson was born in New Zealand in 1976\, and received his Ph.D. in 2003 at The Australian National University where he worked for Prof. Lewis N. Mander. Following postdoctoral studies at Harvard University with Prof. David A. Evans\, he joined the faculty at Northwestern University in 2006 where he is currently a Professor of Chemistry. Regan’s research interests include natural product synthesis and discovery\, and atmospheric chemistry. He is the recipient of an NSF CAREER Award\, an Amgen Young Investigator Award\, a Novartis Lectureship\, and an Illinois Division American Cancer Society Research Scholar Award. At Northwestern he has been named a Charles Deering Professor of Teaching Excellence and awarded the Provost Award for Exemplary Faculty Service.

In this seminar\, I will share my experience moving from graduate training into a postdoc\, focusing on what felt different\, what was challenging\, and what I wish I had known earlier.\nWe will begin with a brief overview of my academic background and how I approached the postdoc application process\, including factors that influenced my decision. I will then discuss key differences between graduate school and postdoctoral work\, such as increased independence\, shifting mentoring dynamics\, and expectations around productivity and ownership of research.\nThe seminar will also include an overview of how I initiated my postdoctoral research. I will present three projects I have worked on\, highlighting the scientific questions\, computational approaches\, and selected results to illustrate how research projects develop in a new environment.\nFinally\, I will reflect on broader topics such as skill development\, work-life balance\, and how I am thinking about future career directions. The goal of this seminar is to provide a practical and honest perspective that may help graduate students better prepare for the transition to a postdoc.

The percolation of adsorbates through the surface raises many fundamental questions\, such as\, what conditions promote subsurface adsorption? Does the same adsorbate have different chemical properties in the subsurface compared to the surface? How do subsurface adsorbates influence chemical reactions on surfaces? To address these questions\, we extended the theoretical framework of lattice-gas models to describe both coverage-dependent surface and subsurface adsorption in crystalline solids. Using this framework\, we developed an all-site DFT-parameterized lattice-gas model for O/Ag(111) and integrated it with Monte Carlo simulations to calculate the thermodynamic distributions of atomic oxygen on the surface and in the subsurface of Ag(111). The results show that subsurface adsorption becomes thermodynamically favorable for oxygen coverages greater than 0.375 ML. Furthermore\, we applied the simulations to construct the first ab initio phase diagram of O/Ag(111) that shows the pressure and temperature ranges within which subsurface oxygen coexists with surface oxygen on Ag(111). Our results indicate that subsurface oxygen is present under the industrial conditions used for the catalytic partial oxidation of olefins on silver nanoparticles. Finally\, we computed the reaction pathway for the conversion of ethylene to ethylene oxide on Ag(111) using DFT and found significant changes to the reaction barriers with increased oxygen coverage and the presence of subsurface oxygen.

DPCs are potent blocks of helicases\, as well as DNA and RNA polymerases. DPCs are associated with aging and diseases such as cancer. Recently\, DPCs were also shown to result in chronic inflammation. Despite their importance\, our understanding of DPCs has lagged that of other forms of DNA damage. For instance\, the first protease identified to repair DPCs in human cells (SPRTN) was only identified in the past decade. Our group is developing chemical tools for producing DPCs. These tools are useful for studying DPCs extra- and intracellularly and are potentially useful pharmacologically. Recent published and unpublished investigations will be presented.

The latter lie at the etiology of disease but is also the goal of many anti-cancer therapeutics. Consequently\, understanding this diverse and important group of processes is of paramount importance. \nFrequently\, scientists focus on the initially formed damage. To understand the consequences of DNA damage and its formation\, our group begins its investigations by using the reductionist approach of organic chemistry. Generating a single damage site (“lesion”) within DNA simplifies studies on DNA damage and facilitates a deeper understanding. Using this strategy\, our research group has discovered          that in some instances the formation of damaged DNA is only the beginning. \nFor instance\, some forms of damaged DNA inactivate repair enzymes. These discoveries provide insight into the chemical bases of drugs that kill cells by producing these forms of DNA damage and inspiration for designing inhibitors of such enzymes. Other DNA lesions react with the histone proteins within nucleosome core particles to produce more biologically deleterious forms of damage. Some of these processes that have been discovered in the test tube have been shown to occur in cells. \nOverall\, combining organic chemistry\, biochemistry and cell biology to study damaged DNA facilitates elucidating these biologically important and complex processes\, the discovery of previously unrecognized pathways\, and the inspiration for designing molecules with useful biological activity.
