Current Group Members |
Sam Kounaves (Ph.D.) (he/him) Sam is a Professor of Chemistry at Tufts University, an Affiliate Scientist at the NASA-Jet Propulsion Laboratory, and a Visiting Professor in the Department of Earth Sciences at Imperial College London. He received his B.S./M.S. from Cal State-San Diego in 1978 and a Ph.D/D.Sc. from Université de Genève in 1985. After post-doc fellowships at SUNY-Buffalo and Harvard University, he joined the faculty at Tufts in 1988. His research interests are in planetary science and astrobiology using the techniques of modern analytical chemistry, with a focus on the search for biomarkers for life on Mars and Enceladus. |

Neveda Naz (Ph.D.) (she/her) Neveda is a Visiting Scholar in the Department of Chemistry at Tufts University. She received her B.S. in Biomedical Science from Manchester Metropolitan University (UK), M.S. in Medical and Molecular Microbiology from the University of Manchester (UK), and her Ph.D. in Microbial Pathogenicity from the London School of Hygiene & Tropical Medicine (UK). After a teaching position at Endicott College (2016-18), she joined the Chemistry Department as a post-doctoral scholar (2018-23) and is currently a Visiting Scholar. Her research interests are in understanding how bacteria can survive in extreme environments such those found on Mars and the icy moons of Jupiter and Saturn (Europa and Enceladus), and what that would mean in the search for extraterrestrial life. |

Bernadette Dineen (she/her) Bernadette is a Massachusetts native who has lived in the Berkshires for the last 8 years. Her research focuses on investigating the fragmentation effects of UV radiation and oxychlorine intermediates on tryptophan under standard Mars conditions using GC-MS analysis. She is also developing ion selective electrodes using novel ionophores for detecting important life-essential compounds on ocean worlds, such as Enceladus! | ||
|
Megan Farrah (she/her) Megan hails from Winfield, Missouri. Her area of research involves design and development of Mars simulation chambers, as well as examining fragmentation patterns of biomarkers under martian conditions. Her next project will focus on studying the production and permeation of organic-destroying chlorine dioxide gas in martian regolith. | ||
|
Kristen (Molly) Twombly (she/her) Molly is a graduate student from Rockport Massachusetts. Presently, her research focus revolves around the fragmentation patterns and pathways of biomarkers induced by UV radiation and oxychlorination in simulated martian environments. | ||
Emma Smith (she/her) Emma is an undergraduate at Tufts from Glastonbury, Connecticut. Her research investigates the breakdown of adenosine under martian conditions using a Mars Simulation Chamber and LC-MS analysis. Emma spends her free time listening to music and playing with all the friendly dogs. She sprints and runs hurdles on the Tufts track team. Emma enjoys indie music, and her favorite color is orange. Her dream job is to work as a field marine biologist.

Madeline Walters (she/her) Madeline is a chemistry and geological sciences undergraduate from Clinton, New York. She is currently working on understanding biomarker fragmentation patterns and pathways caused by UV radiation and oxychlorination under martian conditions. |
||
Rachel Taylor (she/her) Rachel is from the South Shore in Hanover, MA. Her research focuses on the detection of essential elements to life via electrochemical analysis of dilute samples, developing ion selective electrodes for analysis of ocean worlds. She also is about to join the rest of the lab on evaluating biomarker degradation via UV radiation and oxychlorine intermediates. Rachel is co-captain of the Tufts Club Rugby team, and typically plays in the back line. In her free time, she enjoys reading, but can’t choose a favorite book because there are too many! Her favorite food is chicken marsala from either the Cheesecake Factory or her mom’s homemade. Her favorite TV show is BBC’s Sherlock, which she has watched too many times to count! She doesn’t have a specific dream job, but hopes that whatever it is allows her to travel for work. |

Alexander (Alex) Terwogt (he/him) Alex spent the first 18 years of his life in Zierikzee, [the] Netherlands, before moving to Chicago, Illinois. He is working on the installation of a Waters LC-MS instrument for the Kounaves lab, as well as working on the analysis of the fragmentation of adenosine under martian conditions. As for free time, you can always find Alex sitting outside on his balcony enjoying a book, or cooking or baking a new recipe! His favorite book series is Red Rising by Pierce Brown, and he enjoys indie/alt/pop music. His dream job is to become an organic chemist working in small molecule drug discovery or working in astrobiology research! |
