Michael's C.V.

Mac Pierce

Mac was an undergrad lab assistant and participated in the 2015 ADMAC field sampling in Costa Rica.

Hanna Kim

Hanna was a lab assistant, working on morphometrics of the genus Pheidole and involved in DNA library preparation for the ADMAC project.

Spencer Monett

Spencer worked as a lab assistant, providing lots of help sorting ants from leaf litter samples. He was also involved in DNA extraction and library preparation, associated with the ADMAC project.

Alex Gregorcy

Alex became interested in ants and entomology after taking a Costa Rica field class with Jack Longino. He helped sort ants from a conservation-oriented trip in Guyana that Michael Branstetter participated in.

Brendon E. Boudinot

B.S. Evergreen State College, WA (2012)

An avid mountain biker and metal-head, Brendon is one of the few myrmecologists to specialize in male ant morphology and taxonomy, although his research interests also span molecular systematics and functional morphology. His major current project is to produce male-based keys and diagnoses to all the ant genera of Central America. He worked with Dr. Longino since an undergraduate at Evergreen, and was a field assistant for the LLAMA project in 2010 (Honduras). He was a hyper-productive lab tech in the Longino lab at University of Utah, 2012-2013, and has started a PhD program with Phil Ward at UC Davis.
