Thesis: Introduction and Suppression of Amber Stop Codons in the Genome of

Escherichia coli.

Summary: As part of a functional genomics project in the bacterium Escherichia

coli, I developed a number of methods for the directed manipulation of the

genome, particularly the introduction of amber stop codons in essential genes.

The effects of these mutations were turned on and off by the use of a suppressor

tRNA, and the behavior of the resulting conditional lethal mutants were studied

in the context of evaluating different essential genes as targets for the

development of new antibiotics. The transcriptional side-effects from using the

suppressor tRNA were evaluated using microarrays, and a novel regulator for the

oxidation of formaldehyde was identified.

Work Experience

July-Aug 2013 Scientist. Avitide, Inc. Lebanon, NH. Avitide is an early stage start-up working on

purifcation methods for protein therapeutics. I performed general molecular biology

and biochemistry for them on a short-term employment contract.

2011-current Adjunct Associate Professor, Thayer School of Engineering, Dartmouth College,

Hanover, New Hampshire. Co-taught Metabolic Engineering course and co-advised

graduate students with Professor Lee Lynd. I also acted as a liason between Mascoma

Corporation and Dartmouth college to monitor work done under a Sponsored Research

Agreement and was an activity leader at the BioEnergy Science Center.

2006-2013 Senior Research Scientist. Mascoma Corporation, Lebanon, NH. Mascoma is a spin-

off from Dartmouth College that develops biotechnology for conversion of grain and

cellulosic biomass to ethanol, and is particularly known for Consolidated

Bioprocessing. I joined Mascoma when it was a 12-person startup, managed 4-6 people

on a functional basis and directed work on thermophilic bacteria. As co-PI of a $4.9

MM grant from DOE, I helped develop T. saccharolyticum for conversion of pretreated

hardwood to ethanol. I was responsible for OMICs work performed in conjunction

with Oak Ridge National Lab, including microarray and metabolomic analysis.

2004-2006 Postdoctoral researcher. University of California San Diego, Department of

Bioengineering, laboratory of Bernhard Palsson. Projects: 1) investigation of systems

properties in data from gene expression measurements and an integrated model of

metabolism and regulation; 2) analysis of mutations acquired during adaptive evolution

in E. coli; 3) identification of RNA polymerase binding sites throughout the E. coli

genome using chromatin immunoprecipitation and microarrays (chIP-chip).

Summer 2004 Postdoctoral researcher. University of Wisconsin Madison, laboratories of Bob

Landick and Aseem Ansari in the departments of Bacteriology and Biochemistry.

Project: I worked to identify DNA binding sites of transcription factors throughout the

genome using chIP-chip.

Summer 2003 Intern. Scarab Genomics, Madison, Wisconsin. In fulfillment of the internship

requirements of the NIH Biotechnology Training Fellowship, I worked for Scarab

Genomics to engineer industrial strains of E. coli and collaborated with Dr. Bernhard

Palsson at UC San Diego on new strategies for metabolic engineering.

1999-2000 Teaching Assistant. University of Wisconsin, Department of Bacteriology. I

conducted short lectures and oversaw an introductory bacteriology laboratory course

for undergraduates, then assisted in the lectures and supervision of an upper division

undergraduate course in bacterial genetics.

1997 to 1998 Research Technician. University of Melbourne, Australia, Department of Surgery, Dr.

Wendy Cook’s lab. Project: Positional cloning of a tumor suppressor gene involved in

mouse myeloid leukemia.

1993 to 1997 Research Technician. Medical Biology Institute, La Jolla, California, Dr. Roy Riblet’s

lab. Projects: The cloning and characterization of the mouse Immunoglobulin Heavy-

chain (Igh) locus, and the positional cloning of stem cell regulatory genes, the SCID

gene, and the mouse herpes keratitis gene.

Summer 1992 Undergraduate Assistant. University of California, San Diego, Dr. Milton Saier’s lab.

Project: Identification and characterization of the phosphotransferase system of the

pathogen Listeria monocytogenes.

Summer 1991 Chemist. S-Cubed, San Diego, California. Project: Preparation and

spectrophotometric analysis of liquid and soil samples for trace metal contamination.
