Swiss National Science Foundation Early Postdoc Mobility Fellow
Peng was raised in Shandong, China. He earned his Bachelor of Science in Chemistry at Shanghai Institute of Technology, China, in 2012. Thereafter, he joined a joint project between Shanghai Institute of Technology and Shanghai Institute of Organic Chemistry for his Master Thesis on asymmetric addition reactions of chiral α,β-unsaturated-N–tert-butanesulfinyl ketimines. In 2016, he then moved to the University of Fribourg, Switzerland, to pursue his Ph.D. under the supervisor of Prof. Andreas Kilbinger, where he worked on telechelic polymer synthesis by ring-opening metathesis polymerization (ROMP). In 2020, Peng joined the Adolphe-Merkle Institute as a joint postdoctoral researcher in the groups of Profs. Nico Bruns, Michael Mayer, and Christoph Weder, where he investigated block copolymer based aqueous two-phase systems for the generation of electricity as part of the NCCR Bio-Inspired Materials. Peng joined the Robb group in September 2021 as a Swiss National Science Foundation Early Mobility Postdoctoral Fellow. In his free time, Peng likes traveling, hiking, skiing, and fitness.
B.S. in Biochemistry, Indiana University, 2017
NSF Fellow and Barbara J. Burger Fellow
Molly was raised in Evansville, Indiana, along the scenic Ohio River. She earned her Bachelor of Science in Biochemistry as an Indiana University Hoosier while working in the labs of Drs. Laura and Kevin Brown. In a decision only marginally affected by Pasadena’s proximity to Disneyland, she made the 2,000 mile move out west to pursue graduate study at Caltech. In her free time, Molly enjoys searching for LA’s best vegetarian tacos, knitting hats in the only pattern she knows, failing to leash train her cat, and complaining about California’s inferior corn.

B.A. in Chemistry, Johns Hopkins University, 2015
Ross grew up in snowy Fayetteville, New York. He attended Johns Hopkins University and researched fluorination methods under the guidance of Prof. Thomas Lectka. After graduating with a Bachelor’s in Chemistry, he moved to Worcester, Massachusetts to join the team at Microbiotix, Inc., developing small molecule antibiotics and antivirals. Identifying more closely with long molecules, he left Massachusetts for sunny Pasadena to study polymer chemistry with Professor Robb. For fun, he likes to carry all of the groceries up the stairs in one trip, go outside on a 60 degree day and not be cold, and put 10 mL beakers on the tips of his fingers.

B.A. in Chemistry, Cornell University, 2018
NSF Fellow, Institute Fellow, and Barbara J. Burger Fellow
Anna grew up in Zionsville, PA. She earned her Bachelor of Arts in chemistry at Cornell University. During her time at Cornell, she worked for Professors Will Dichtel and Geoff Coates, working first on covalent organic frameworks and then on epoxide polymerization. After four years spent without seeing the sun, she visited Pasadena and realized a different sort of life was possible. She now spends her free time bouldering, petting strangers’ dogs, enjoying good food, and trying to become a better cook to facilitate the eating of good food.

B.S. in Chemistry, Texas A&M University, 2018
Brooke was raised in College Station, TX. She earned her B.S. in Chemistry from Texas A&M University, where she investigated the synthesis of polycarbonates from naturally-derived building blocks under the direction of Prof. Karen Wooley. When not in lab exploring structure-property relationships in mechanochromic polymers, Brooke enjoys participating in science outreach activities, baking, and searching Pasadena for the perfect cup of coffee.

A.B. in Chemistry, Harvard University, 2017
Corey grew up in rural Kunkletown, Pennsylvania. He then went on to Harvard University, where he studied chemistry with a minor in astrophysics. While there, he worked under Prof. George Whitesides studying mechanisms of peptide polymerization in low-melting salt mixtures with implications for the chemical origins of life. After college, Corey spent much of his next year living in the mountains of southwestern Uganda and then in Indonesian Borneo. However, a bout of dengue fever and the excitement of graduate school eventually brought him back stateside. For fun, Corey enjoys being outdoors, cross-tuning his fiddle, and eating pie for any meal of the day.

Tian (May) Zeng
B.S. in Chemistry, University of California, San Diego, 2018
May grew up in Wuhan, Hubei, China, before flying over the Pacific Ocean to earn her B.S. in Chemistry from UCSD. While there, she spent two years in Prof. Keary Engle’s lab at the Scripps Research Institute (TSRI), just 30 mins away. At TSRI she studied directed Pd-catalyzed alkene difunctionalization reations, while catching sunsets on the ocean across the Torrey Pines golf course. After graduation, she spent a summer working as an intern for the Discovery Chemistry department at Genentech, South San Francisco, before heading back to the warm embrace of southern California. Outside of lab, May likes to travel, dance, cook, watch TV shows, and attempt to learn painting.

Meng (Stella) Luo
B.A. in Chemistry, Macalester College, 2020
Stella grew up in Beijing, China. She earned her BA in Chemistry at Macalester College in Minnesota. During her undergrad, Stella worked with Professor Dennis Cao on molecular organic semiconductor materials. She decided to move to Southern California for the sunshine and the food after 4 years spent in the snow. In her free time, Stella enjoys singing and searching for good Asian food, or both at the same time. She also makes constant attempts to play video games, cook, and watch TV dramas.
