Ontario Tech acknowledges the lands and people of the Mississaugas of Scugog Island First Nation.

We are thankful to be welcome on these lands in friendship. The lands we are situated on are covered by the Williams Treaties and are the traditional territory of the Mississaugas, a branch of the greater Anishinaabeg Nation, including Algonquin, Ojibway, Odawa and Pottawatomi. These lands remain home to many Indigenous nations and peoples.

We acknowledge this land out of respect for the Indigenous nations who have cared for Turtle Island, also called North America, from before the arrival of settler peoples until this day. Most importantly, we acknowledge that the history of these lands has been tainted by poor treatment and a lack of friendship with the First Nations who call them home.

This history is something we are all affected by because we are all treaty people in Canada. We all have a shared history to reflect on, and each of us is affected by this history in different ways. Our past defines our present, but if we move forward as friends and allies, then it does not have to define our future.

Nisha Agarwal received her PhD from Politecnico di Milano, Milan, Italy in 2013 as an Erasmus scholar working in the field of nanotechnology and materials science focusing on Surface Enhanced Raman Scattering (SERS). She further pursued 5 years of post-doctoral research at Istituto Italiano di Tecnologia, Genova, Italy; Chalmers University of Technology, Gothenburg, Sweden and McMaster University, Hamilton, Canada broadening her expertise in non-linear microscopy with applications in plasmonics, pharmaceutical and biological sectors, development of super-resolution techniques and paper-based point-of-care diagnostics. She currently holds an Assistant Professor position in Physics, Faculty of Science at Ontario Tech University, Oshawa, Canada.

Her main research interests lie in innovation and development of new emerging high-resolution (nanoscale regime) technologies and integrating it with Atomic Force Microscopy (AFM) and Raman spectroscopy. The technology is applied to solving real-world problems such as biological study of neurological disorders, Alzheimers and Parkinsons disease; mitochondrial dysfunctional studies in yeast cells as a model for Alzheimers, study of metastasis in colo-rectal cancer cells and environmental problems. Additionally, the applications extend to understanding physical phenomena at the interfaces of nanomaterials, thus building the field of plasmonics.
