Researcher and DOE liaison in the Materials & Components Analysis (MCA) department.Studied the morphological, mechanical, and electronic properties of novel systems by various SPM modes, with a focus is on new and difficult to measure materials and devices. As DoE liaison, I developed strong rapport with scientific leads to understand their research and.

Leuven, Belgium

Postdoc in the SPM group within the materials characterization department at IMEC. In this role, I had the opportunity to collaborate with a variety of programs (logic, memory, batteries) to design and lead projects to characterize the morphological and electronic properties of novel materials with SPM. One of the primary functions was to work closely with.

Tallahassee, Florida Area

Coordinate high magnetic field FTIR experiments with a rotating group of external scientists visiting every 1-2 weeks. Provided technical support, design of experiment, and data analysis expertise. Responsible for ensuring that experiments were successful. Requiring communication and quick troubleshooting to find solutions when issues arose or equipment.

• Designed and directed experiments to study the electronic properties of novel semiconductors by optical-spectroscopy and electrical-transport at low temperatures and high magnetic fields. Primary systems.
• Visible (VIS) and infrared (IR) spectroscopy: Raman, photoluminescence, photoconductivity, FTIR.
• Electrical transport: DC and AC techniques, Hall Shubnikov-de Haas (SdH), quantum Hall.
• Extensive experience with free-space and fiber optics, polarization control and lasers.Optical systems development:
• Developed optical fiber based probe for polarization-resolved micro-spectroscopy of atomically thin devices at low temperatures (down to 300mK) and high magnetic fields (up to 31T). This involved working with vendors.
• Modified standard Olympus optical microscope for quick spatially resolved micro-spectroscopy and electrical characterization of atomically thin devices.

• Growth and characterization of complex oxide thin films
• Synthesized Mott insulating films with applications to high quantum efficiency solar cells.
• Studied low temperature magneto-transport of the 2DEG at the interface of LaAlO3/SrTiO3. Development:
• Helped design and build lab from the ground up for growth and characterization of high quality complex oxides by molecular beam epitaxy (MBE). This involved dismantling and shipping two MBE chambers from Penn State to.
• Designed and built probe for quick electrical characterization of thin film samples down to liquid He temperatures (4.4K).
• Automated data acquisition by writing LabView program to control Keithley current source and nano-voltmeter. Materials characterization techniques:Electrical transport, optical absorption spectroscopy, atomic force.
