Research
My primary interest lies in computer graphics; specifically, the study of effective virtual environments. I believe that computer graphics improve the way we learn and understand the world around us. In my work, I seek to create virtual environments that are general learning environments and explore novel methods for humans to experience these environments. My research can be categorized into desktop virtual environments and immersive virtual environments. My desktop virtual environment research has focused on incorporating an effective animated agent and media into a biology tutoring system, Guru (). My work in immersive virtual environments involves viewing a three-dimensional world through a head-mounted display (HMD). A major part of this research involves understanding the cognitive capabilities of humans in virtual environments. Even state-of-the-art virtual environments are usually unconvincing, and people have difficulty organizing their spatial knowledge of them and moving around in them. One goal of my research is to improve our understanding of how people perceive and reason about space in a virtual environment and how that understanding can be technically leveraged into an improved interface.
Outside The Classroom
I joined the ÎÚÑ»´«Ã½ faculty in Fall 2007. I grew up in Inverness, Mississippi, which is a speck of town in the Mississippi Delta. I received my undergraduate degree in mathematics and computer science from Millsaps College, a liberal arts college in Jackson, Mississippi. I then completed my master′s degree and Ph.D. in computer science at Vanderbilt University in Nashville, Tennessee.
I live in Midtown Memphis with my husband Andrew Sanders (a 2001 ÎÚÑ»´«Ã½ graduate) and two dachshunds GiGi and Lucy. GiGi is a famously fast hound who has been known to put her racing skills to the test by winning prize money for the Computer Science Club. When GiGi and Lucy aren′t training, they are being chased by our toddler daughter Callie whose first word was "dog". In my free time, I enjoy cooking and more importantly, eating. Our home is over 100 years old, and it seems like something ALWAYS needs fixing so I have become quite handy. I love antique shopping, too!
