STEM Librarian, Ph.D., MLIS
Hi There And Welcome To My Corner!
I am STEM librarian at Harriet Irving Library. This is my first time working at UNB having previously worked in the Engineering & Science Library at Queen's University in Kingston ON. My background is interdisciplinary and my academic portfolio contains multiple publications in peer-reviewed journals. I am currently responsible for six departments including Earth Sciences, Mathematics & Statistics, Chemistry, Biology, Forestry & Environmental Engineering, and Physics. In addition to the traditional liaison librarian responsibilities, I am interested in research data curation, which includes many different aspects such as data repositories, data documentation, data management plan writing, data sharing, data ethics. As an example, within the library, we have a Dataverse repository, where research data can be deposited and a DOI can be assigned to a data set. My intention is to structure research data management services at the library that they are relevant and in line with research topics at UNB.

Computational Biophysics. In 2012 I joined the photobiology group at Brock University to participate in a project aimed to understand the mechanism of substrate permeation in Photosystem II (PSII). Our approach was to use Molecular Dynamics simulations in solving the mysteries of substrate permeation. This approach required outstanding computer power such as SHARCNET High Performace Computers (HPC) to perform massive computer simulations and modeling. Photosystem II (PSII) is the enzyme that catalyzes the oxidation of water (2H20+light->O2+4H) in oxygenic photosynthesis. It has the remarkable ability to tap into an abundant energy supply, sunlight, and water, to ultimately power most forms of life. The efficiency and rate of water oxidation in PSII are unmatched by any artificial system, yet, the mechanistic details are not well understood. The large size and complexity of PSII are the factors that have slowed down progress towards an understanding of this fundamentally important process. The active site of water splitting is protected and stabilized by being buried deep within PSII. Although previous studies have identified several channels within PSII, it is unknown how substrate and products move within those channels. By using Molecular Dynamics (MD) simulations we calculated free energies of permeation of the substrate, and several inhibitors through PSII. Two MD techniques were applied: steered molecular dynamics (SMD) and umbrella sampling. This work revealed how PSII optimizes binding and orientation of the substrate (water) and restricts the access of unwanted inhibitors.
Medical Imaging. In 2004-2006 I have been working as a post-doctoral fellow at Brain and Body Institute (BBI), St. Joseph’s Healthcare Hamilton (lab of Dr. Michael Noseworthy). BBI at SJH has a state of the art Imaging Center with 3Tesla 8 channel GE MRI system. My work was aimed at developing imaging methods for diagnosis of the sport-related musculoskeletal injuries. One of the techniques I used was diffusion tensor MRI (DT-MRI). In fibrous tissue, such as muscle, diffusion MRI provides estimates of fiber orientations in each image voxel and thus allows post-processing algorithms to reconstruct global fiber trajectories and infer global connectivity. I used DT-MRI and the fiber tracking algorithm to demonstrate the extent of the injury within the muscle tissues. Another project at BBI was aimed at a characterization of the temporal changes in the musculoskeletal structure after acute muscle injury by means of DT-MRI. In this project, imaging results were compared with the standard clinical test, based on the measurements of blood serum creatine kinase. Patients with acute muscle injuries were recruited from the local Rehabilitation Center. Projects were conducted in a close collaboration with Dr. Dinesh Kumbhare (McMaster Rehabilitation).
