Clemens Alt, PhD
I research lasers in ophthalmology for therapeutic and diagnostic purposes. My interests include therapeutic selective targeting of ocular cells (e.g., retinal pigment epithelium cells) for the treatment of retinal diseases, adaptive-optics scanning laser ophthalmoscopy and in vivo retinal flow cytometry.

My research here at Wellman will focus on tracking cells in live tissue with in vivo imaging techniques, trying to understand the role of progenitor cells and inflammatory cells in tissue repair following injury, and develop therapeutic strategies to promote tissue repair.

Joel Spencer, PhD
Research Fellow
I am interested in the development and application of intravital microscopy to study mesenchymal stem cell homing to various tissues, T cell response to islet transplants, and several other topics. My interests also include the development of in vivo optical methods to study the role of oxygen in the homing and retention of hematopoietic stem cells to bone marrow.

Research Fellow
I am researching two-photon microscopic in-vivo imaging implemented with adaptive optics to enhance penetration depth and two-photon flow cytometry.

Visiting Graduate Student
I study how systemically infused adult bone marrow-derived mesenchymal stem cells (MSC) home to sites of inflammation. MSC have been shown to exert immunosuppressive effects in multiple models of inflammatory disease. Using intravital microscopy, I hope to elucidate the MSC homing mechanism, and dynamics of immunosuppression.
Raphael Turcotte
Graduate Student
My current research focuses on the development of optical tools to probe and interact directly with the bone marrow of live animals. Guided by optical microscopy, I seek to modify and analyze the hematopoietic stem cells microenvironment in the bone marrow at the single cell level.

Research Fellow
My research focuses on the systemic hematopoietic response during leukemic development. Combining a multicolour genetic model and in vivo high resolution imaging, we track the clonal response of the hematopoietic system during malignant transformation and their interaction with cancer cells. Such information will be critical for improving future strategies against hematopoietic malignancies.
Walid Zaher, MD
Research Assistant
My research is centered around investigating the mechanisms that govern mesenchymal and hematopoietic stem cells homing after transplantation. Using confocal microscopy, we are also investigating the role of endogenous (resident) stem cell population and their cross talk with the injected MSC and HSC in the bone marrow after irradiation and their role in bone marrow reconstitution.
