1998-Spring 2002 Biology with Honors and Distinction
Iowa State University GPA: 3.63/4.0


August 2003 – Present: Doctoral Candidate, Department of Microbiology, Montana State University, Laboratory of Dr. Gill Geesey
Research Summary/Projects:

1. Characterization of microbial colonization patterns on artificial substrates in situ and subsequent community structure analysis using fluorescent in situ hybridization (FISH) in an acid-sulfate-chloride (ASC) hot spring community

2. Enrichment isolation and characterization of microbes involved in reductive sulfur metabolism using innovative flow-cell and chemostat strategies

3. Characterization of solid phases associated with microbial mat samples
involved in sulfur cycling using a combination of analytical spectroscopic techniques

4. Comparative Stratiomys species gut and adjacent mat microbial community analysis in an ASC hot spring community
August 2002-July 2003: Research Associate II, Department of Microbiology,
Iowa State University, Laboratory of Dr. Alan A. DiSpirito
Research Summary/Projects:
1. Improvement of the purification procedure for the membrane-associated methane monooxygenase (pMMO) from Methylococcus capsulatus Bath
2. To develop the use of microbial fermentation to convert bio-based synthesis (syn) gas to value-added products like fuels, chemicals, lubricants, or plastics. Syn gas is produced through thermal gasification of many feedstocks such as coal, oil, biomass, or organic waste material , the primary components of syn gas are CO and H2. Current focus is on polyhydroxybutyrate (PHB) and polyhydroxyvalerate (PHV) from Rhodospirillium rubrum

Research Summary/Projects:

1. Toxicity screenings and IC50 for sulfonamide antibiotics and herbicides on Bradyrhizobium japonicum
2. Preliminary GFP conjugation matings between Echerichia coli and Bradyrhizobium. japonicum as a tool for toxicity screenings
