Peter Buck Postdoctoral Fellow, Mineral Sciences Department, National Museum of Natural History, Smithsonian Institution, 2015-2017:
Mycogenic Mn oxide phase transformation behavior and effects on trace metals.
Research involves the investigation of initial and secondary mycogenic Mn oxide precipitates via diffraction analyses and transmission X-ray absorption fine structure (XAFS) spectroscopy, and the speciation of trace metals (Ni, Zn, Co, and Cr) upon aging the solid precipitates via wet chemistry analyses and fluorescence-yield XAFS spectroscopy.

Ph.D. Candidate, Earth & Planetary Sciences Department, Washington University, 2010-2015:
Mn(II) interactions with trace metals & Mn oxides. 
Research consisted of obtaining trace metal (Ni) adsorption isotherms by analysis of element concentrations with inductively coupled plasma-optical emission spectroscopy (ICP-OES) and determining the effect of Mn(II) on the speciation of Ni, Zn, Co, and As(V) associated with solid Mn(IV/III) oxides by fluorescence-yield XAFS spectroscopy.

Effect of aqueous Mn(II) on Mn oxide structures.
Research entailed synthesizing environmentally-relevant Mn oxides, characterizing synthesized Mn oxide materials by BET and Mn oxidation state determinations, preparing Mn(II) adsorption isotherms by analysis of element concentrations with ICP OES, and identifying the effects of Mn(II) on Mn(IV/III) oxide oxidation state using transmission X-ray absorption near edge structure (XANES) spectroscopy and on Mn(IV/III) oxide structures using transmission extended X-ray absorption fine structure (EXAFS) and powder X-ray diffraction (XRD).

Fe(II) interactions with oxoanions, Ni & Fe oxides. 
Research involved synthesizing metal-substituted and pure Fe(III) oxides, characterizing synthesized Fe oxide materials by BET and fractional dissolution measurements, preparing Fe(II), phosphate, sulfate, and Ni adsorption edges/isotherms by analysis of element concentrations with ICP-OES and sulfate concentrations with ion chromatography (IC), determining changes to molecular configurations of oxoanions by obtaining and fitting attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectra, and identifying changes to Ni speciation by XAFS spectroscopy.

Undergraduate Research Assistant, Chemistry Department, Sewanee, 2008–2009:
Solution aggregation of bipyridine Pt(II) complexes. 
Research focused on solution aggregation of bipyridine Pt(II) complexes via intramolecular metal-metal interactions hypothesized to be important in producing their photoluminescent and polymorphic behavior. Research duties consisted of synthesis and analysis by nuclear magnetic resonance (NMR) spectroscopy and ultra-violet visible (UV-vis) spectroscopy.

I. Croom Beatty Research Internship, Chemistry Department, Sewanee, 2008:
Kinetic behavior of Au(I) thiolate complexes.
Investigated the rate and order of a novel ligand exchange reaction in gold thiolate complexes. Duties included analyzing Au(I) thiolate complexes with time-dependent UV-vis spectroscopy.
