While completing her Ph.D. at the University of Waterloo she was very involved in research on IP Mobility, and eventually her thesis was based on that subject. Her interest has now shifted to routing in LLN (low-power and lossy networks) and vehicular networks. Sandra routinely shares the experiences and information gathered at IETF with her students and professional networks, and is an advocate for greater participation in the IETF from academia. Sandra is a Returning Fellow, having previously been selected for IETF's 69, 76, 79, 83, and 87.
