My lab studies protein folding and biomolecular engineering. Our goal in these endeavors is both an improved understanding of the folding process and an ability to apply this rapid, highly specific, highly cooperative self-assembly process to the development of nano-scale electronic sensors and adaptable materials.

Postdoctoral Scholars and Fellows


Martin KurnikMartin
Ph.D. ’13 from the University of Stockholm in Sweden in Biochemistry
mkurnik (at) chem.ucsb.edu

I am developing a new, quantitative approach for measuring how proteins and nucleic acids interact with different artificial surfaces, including biomimetics. The resulting experimentally derived models of surface-interaction thermodynamics will facilitate design of new, optimally biocompatible materials for implants, tissue engineering scaffolds, drug delivery nanoparticles, biosensors, and other biotechnologies. My work also has a fundamental scientific motivation: we cannot comprehend the molecular biology of the cell without understanding how its contents remain in solution despite proximity to a multitude of membrane surfaces.


Hui LiHuiLi
Marie Curie Fellow
Ph.D. ’13 from University of Berne in Switzerland in Material Chemistry
huili (at) chem.ucsb.edu

My research interest is to develop electrochemical DNA biosensors (E-DNA) for real-time, continuous measurements of clinic relevant drugs and biomakers in whole blood in vitro and in vivo.


Netzahualcóyotl ‘Netz’ ArroyoNetz
Otis Williams Postdoctoral Fellow
Ph.D. ’15 from University of Texas Austin in Chemistry
narroyo (at) chem.ucsb.edu
netzarroyo.org

My research focuses on the development of electrochemical-aptamer based sensors (E-AB sensors) for the real-time, continuous monitoring of target molecules in undiluted whole blood and brain tissue in vitro and in vivo. The dream goal of my project is to achieve time resolved measurements of pharmacokinetics in the brain.


Philippe Dauphin DucharmePhil
Ph.D. ’15 from McGill University in Chemistry
pducharme (at) chem.ucsb.edu

I am working in expanding the ability of the electrochemical-DNA (E-DNA) biosensors to detect a wide variety of ions such as Na+, K+, adenosine triphosphate and even small molecules such as glucose and cholesterol! This is done by using non-covalent interaction and principles of supramolecular chemistry. Eventually, the goal of this project would be to test this new class of E-DNA biosensor for their clinical utility in finger-prick volumes of whole blood.


Claudio Parolo
Beatriu de Pinós Postdoctoral Fellow
Ph.D. ’13 from Autonomous University of Barcelona in Biotechnology
claudio.parolo (at) gmail.com

My general research interest is the development of cheap and easy-to-use biosensors for diagnostics applications. I am currently working on the integration of electrochemical DNA sensors into a paper-based electrode. The final goal is the development of a multiplexed device to detect HIV and Syphilis biomarkers in real samples.


Gabriel Ortega
Ph.D. 2015 from the University of Basque Country & CIC bioGUNE in Molecular Biology and Biomedicine

gortega (at) chem.ucsb.edu

Proteins are nature’s choice for most biological functions, but when it comes to biotechnological applications, we are not yet able to make use of their full potential. This is partially because proteins often unfold, adhere to, and inactivate on artificial surfaces. My research focuses on developing models of protein-surface interactions of sufficient detail and accuracy as to guide the design of surfaces on which attached-proteins retain their native fold, their function, and any relevant conformational changes. My ultimate goal is to use this knowledge to design protein-based electrochemical biosensors.
