Congratulations to Komadhie, Atreyee and Amaya for the awards they received in the ISU Chemistry Award Ceremony 2023.

Komadhie: Alpha Chi Sigma Research Award Atreyee: Women in Chemistry Award Amaya: ISU Teaching Excellence Award

The group is excited to welcome the two new post-docs – Alexandra and Fariyad!

Recent paper out of Journal of Organic Chemistry from Pradeep, Atreyee and Komadhie: “Efficiency of Functional Group Caging with Second-Generation Green- and Red-Light-Labile BODIPY Photoremovable Protecting Groups”.

Our group’s collaborative paper with Dr. Peter Seeberger was recently published in Chemical Communications: “Photo-labile BODIPY protecting groups for glycan synthesis”. Congratulations to Komadhie!

Congratulations to Dr. Elizabeth Gehrmann for successfully defending her Ph.D. She is starting as a synthetic chemist at Samsara Eco in Australia.

Congratulations Dr. Ding Yuan for defending her PhD! Ding is off to San Francisco to work as a scientist at Element BioSciences.

Congrats to all of the Winter Lab for the awards they received in 2022!

Ding: Women in Chemistry Award

Liz: Althea Sleight Graduate Fellowship

Komadhie: Arthur P. Hellwig Memorial Scholarship

Atreyee: Teaching Excellence Award

We are looking for a new postdoc to study problems in photochemistry using laser spectroscopy. 50K/yr plus benefits. Apply here!

We had three new graduate students joining the lab in the fall – welcome Yamudith, Qasim, and Madelyn!

Congrats to Dr. Rui Zhang for defending! She is off to UIUC as a post-doc under Dr. Jeff Moore and Dr. Ying Diao

Recent paper out of Journal of Organic Chemistry from Ding and Julie: “Multiwavelength Control of Mixtures Using Visible Light-Absorbing Photocages”

Our NSF grant is highlighted on the college website

Congratulations to Dr. Julie Peterson, Dr. Josh Peterson, & Dr. Yunfan (Frank) Qiu for receiving their PhDs! Julie and Frank are off to do post-docs at the University of California – Santa Barbara and Northwestern University, respectively. Josh is off to New Jersey working for the Department of Health.

Our group’s collaborative paper with Dr. Emily Smith’s group was recently published in JOC: “Direct Photorelease of Alcohols from Boron-Alkylated BODIPY Photocages”

A recent collaboration with Dr. Jeremy J. Kodanko at Wayne State University produced a paper in ACS Chemistry Biology: “BODIPY-Cased Photoactivated Inhibitors of Cathepsin B Flip the Light Switch on Cancer Cell Apoptosis”

New publication out of Angewandte Chemie from Rui: “Anti-Aromaticity Relief as an Approach to Stabilize Free Radicals”

Congrats to Dr. Logan Fischer and Dr. Pradeep Shrestha for defending their PhDs! Logan is off to teach organic chemistry lab at Middlebury College in Vermont while Pradeep is going to start a postdoc at the National Cancer Institute.

WinterGreen photocages are now available at Millapore Sigma

Recent paper out of Organic Letters from Josh: “Solvent-Responsive Radical Dimers”

Congrats to all of the Winter Lab for the awards they received this year!

Josh: Research Excellence Award

Liz: Teaching Excellence Award

Pradeep: David N. and Minnie I. Wall Graduate Scholarship

Frank: Alpha Chi Sigma Award

Our group’s research on dicyano-radicals and pi dimers was recently published in JACS: “Spin Delocalization, Polarization, and London Dispersion Forces Govern the Formation of Diradical Pimers”

Art has been promoted to full Professor!
