She subsequently earned her Ph.D. in Biochemistry and Cell Biology from Rice University. Her dissertation was entitled, “Molecular and Genomic Analyses in Clostridium acetobutylicum.” When not pursuing academic interests she enjoys spending time with her family, traveling, reading, and experimenting in the culinary arts.


Tiffany Travis

Tiffany was born in Maine and raised in Connecticut before venturing her way to Boston for college where she fell in love with the city. Thanks to her dedicated science teachers over the years, she found herself passionate about the wonders of science. She earned a B.S. in Biochemistry in 2010 and her MAT in Secondary Education in 2014, both at Northeastern University. Tiffany has experience in both the research and education fields. She completed a unique trip with SEA Semester during which she sailed aboard a tall ship where she learned sail handling and researched the effect of ocean acidification on pteropods. Tiffany has also worked at two pharmaceutical companies as a co-op during undergrad and then worked her initial few years out of college at Joule Unlimited Technologies where she helped run small-scale bioreactors and cultured various strains of cyanobacteria used in production runs to synthesis non-biomass based ethanol as a byproduct of photosynthesis. After quickly realizing she loved helping others and seeing them learn, she moved on to teach high school chemistry and biology. She’s looking forward to sharing her passion for science and drive for learning with other students through Science from Scientists! In Tiffany’s spare time, she loves to bake, read, and travel. She’s also an avid runner and hopes to run the Boston Marathon in the near future.


Dr. Norah Warchola

Dr. Warchola earned her Ph.D. from Stony Brook University where she studied butterflies and how they move through fragmented landscapes. While at Stony Brook she taught a variety of classes including behavioral ecology and field ecology. Her current research at Tufts University focuses on endangered butterflies and how habitat management affects their behavior and reproduction. When she’s not chasing butterflies, Norah loves doing outreach and telling the public some of the reasons butterflies are so neat. In her spare time she enjoys walking in the woods, arts and crafts, pickling any vegetable that comes her way and baking wedding cakes.


Dr. Cricket Corwin Wilbur

Dr. Wilbur has a doctorate in Environmental Studies from Antioch University New England, a MS in Geology from North Carolina State University, and a BS in Geology from St. Lawrence University. In her doctoral research Cricket investigated factors governing climate change by reconstructing a 10,000-year record of vegetation on an island in southwest Alaska to assess regional environmental changes and global connections. Cricket is an AmeriCorps alumni having served with Essex County Greenbelt Association through the Massachusetts Land Initiative for Tomorrow-AmeriCorps program. She has extensive experience teaching science in diverse environments from inside classrooms and laboratories to outside in the field. Cricket spends her free time enjoying the outdoors with her family, and volunteering with conservation organizations including serving on the board of directors of her neighborhood homeowner’s association.
