Dr. Michael A. Boreen

Postdoctoral Researcher

Michael graduated from the Vagelos Scholars Program in the Molecular Life Sciences at the University of Pennsylvania with a B.A. in Chemistry and Biochemistry and a M.S. in Chemistry in 2015 and performed undergraduate research with Professor Eric J. Schelter. In 2020, he received his Ph.D. in Chemistry from the University of California, Berkeley under the supervision of Professor John Arnold. His Ph.D. research focused on small molecule reactivity and strong bond activation with low-valent uranium complexes. He is currently a postdoctoral researcher in the groups of Professors Alexander Katz and John Arnold at UC Berkeley. Outside of the lab, Michael tries to get in as many ski days as possible and also enjoys bouldering, hiking, and tennis.


Dr. Franck Ulm

Postdoctoral Researcher

Originally from Strasbourg in France, Franck graduated in 2016 from the European School of Chemistry, Polymers and Materials with a M.S. in Molecular and Supramolecular Chemistry. In 2019, he received his Ph.D. in Chemistry from the University of Strasbourg under the supervision of Professor Vincent Ritleng and Professor Michael Chetcuti. As a Ph.D. student, he studied the synthesis and the application of well-defined nickel complexes for the understanding and the optimization of hydrofunctionalization and C-H activation reactions. Currently,  he is a postdoctoral researcher in the group of Professor John Arnold at UC Berkeley through the Fulbright program. Outside of the laboratory, you can find Franck exploring the Bay on his bike or practicing Crossfit.

Jade Fostvedt

Graduate Student

Jade received her B.S. in chemistry from the University of South Dakota in May of 2017. As an undergraduate, Jade studied frustrated Lewis pair chemistry in Dr. James Hoefelmeyer's lab. Jade joined the Arnold lab in fall 2017 and she is investigating low-valent tantalum complexes for potential applications in multi-electron reductive transformations of strongly bonded, small molecule substrates, such as N2, CO, and CO2. Jade is also extraordinarily passionate about science education, both formal and informal, from K-12 to the graduate level. She is the recipient of numerous teaching awards, teaches hands-on chemistry lessons for second grade students through the BASIS program, and is a member of the BASIS steering committee, representing the College of Chemistry. Outside of the laboratory, Jade enjoys yoga, skiing on frozen and liquid water, knitting, and mountain biking.

Erik Ouellette

Graduate Student

Originally from Colorado, Erik graduated in 2018 with a B.A. in chemistry from College of the Holy Cross in Massachusetts. As an undergrad, Erik worked in the lab of Prof. Bianca Sculimbrene utilizing chiral titanium catalysts for the enantioselective phosphorylation of diol molecules. He also spent a summer at the National Renewable Energy Laboratory through the DOE SULI program, under the direction of Dr. Mark Nimlos and Dr. Nolan Wilson, studying the synthesis of novel polycarbonates from renewable feedstocks. Erik joined the Arnold group in the fall of 2018 and is investigating the reactivity of rhenium BDI complexes. Outside of lab, you can find Erik mountain biking throughout the Bay Area and skiing up in Tahoe or wherever the snow is deep.

Joe Brackbill

Graduate Student

Joe received his B.A. in biochemistry from Dartmouth College in June of 2018. At Dartmouth, Joe studied the electron-transfer reactivity of a di-heme cytochrome in the lab of Dr. Ekaterina Pletneva. Joe joined the Arnold group in October of 2018 and is studying the bonding and reactivity of main group-actinide systems. Aside from chemistry, Joe enjoys rowing, biking, and listening to classical music.

Christopher Ye

Graduate Student

Chris received his B.S. in chemistry from Harvey Mudd College in 2019. As an undergraduate, Chris studied dechlorination mechanisms for bio-inspired nickel and cobalt catalysts in the lab of Prof. Katherine Van Heuvelen and chiral titanium catalysts for asymmetric hydroamination reactions in the lab of Prof. Adam Johnson. Chris joined the Arnold lab in the fall of 2019. Outside of chemistry, Chris enjoys playing basketball and tennis, doing puzzle hunts, and solving the daily NY Times crossword.

Jacob Branson

Graduate Student

Jacob received his B.S. in chemistry from Florida State University in May of 2019. During his undergraduate, Jacob worked on the synthesis and characterization of f-element molecular compounds with Prof. Thomas Albrecht-Schmitt. He joined the Arnold lab in Fall 2019 as a joint student with Dr. Stefan Minasian at Berkeley Lab. In his free time, Jacob can be found hiking followed by a brewery.

Sheridon Kelly

Graduate Student

Sheridon received her B.S. in chemistry from Colorado State University in May 2020. As an undergraduate, Sheridon studied surface-interface interactions of imidazolium-based ionic liquids with Dr. Amber Krummel. She joined the John Arnold lab in Fall of 2020 as a joint student with Dr. Stefan Minasian at Berkeley Lab. Outside of the lab, Sheridon loves to bake goods she saw on the Great British Bake Off, read books stolen from her friends’ bookshelves, and photograph people & landscapes with a camera way above her skill level.


David Hales

Graduate Student

David received his B.S. in chemistry and applied physics from the University of Washington in 2020.  As an undergrad, David worked on exfoliating black phosphorus with molten salts and metallating black phosphorus with rhenium carbonyl precursors under Prof. Alexandra Velian.  David joined the Arnold group in Fall 2020 and is investigating strategies to generate rhenium-main group element bonds.  Outside of lab, catch David biking up big hills, playing clarinet, throwing a frisbee, reading sci-fi, or remarking on how nice the weather is in Berkeley.

Anukta Jain

Undergraduate Researcher

Anukta is a third year undergraduate Chemical Engineering major. She joined the lab during the summer of 2019 and works with Jade. Anukta is involved with ChemE Car and Engineers without Borders, and in her free time loves to hike in and around Berkeley, play soccer, and watch dramas on Netflix.

Sandra You

Undergraduate Researcher

Sandra is a second year undergraduate student studying chemistry. Sandra joined the Arnold lab in Fall 2020 and works with Joe. In addition to chemistry, Sandra is interested in data science and learning new languages. Aside from academic studies, Sandra enjoys singing, hiking, traveling and playing badminton.
