Who am I? Biomedical Engineering Ph.D. Student Means:

Who am I? Biomedical Engineering Ph.D. Student Means: Ive been in school a LONG time. Guess? I like school/learning! More fun than work. (One reason to stay in school!) What is a Ph.D.? You learn about doing

research/finding new things Put Dr. before your name What is Biomedical Engineering? Any guesses? Can you guess what I research? Do any of you have interests in engineering? Science? Arts? Help with showing college requirements for each

Cardiac pacemaker. Can you guess what it does? (Ill explain more on the next slide). Adapted from the Wikimedia Commons file " St_Jude_Medical_pacemaker_with_ruler.jpg http://en.wikipedia.org/wiki/File:St_Jude_Medical_pace maker_with_ruler.jpg My research Investigating cell growth Trying to grow organs I like Heart/Muscle Also use nanotechnology

Do any of you know of any nano-devices? Devices that use nanotechnology? Some of you use at least one everyday What can we do if we grow organs? Who can we help? Cells! Can you guess what kind of cells? My research: cells grown at 325m channel m channel spacing, 4x magnification, 59.4m channel m/hr growth rate

0 Hours 2 Hours 6 Hours 23 Hours 4 Hours 25 Hours So what did all of those numbers 325m mean?

channels 325m channel size? Width of cells! 0.032m technology used to make computer chips! 59.4m/hour growth rate Relative to: Your hair grows about 417m per day! Scientific notation? 4x magnification Confusing math equation Basically4x of your normal

eyesight 250mm from your eye = focus distance Cells! Can you guess what kind of cells? Growing Different Shapes (Triangle) Cells from my lab grown to form a heart shape Fun facts! Everyday I come in, Ill try to have some interesting news in science/engineering. Maybe Ill discover something in my research to bring in!

You can also ask me science questions and Ill try to find them out! For example: Have we cured cancer? Answer: No, but were getting close! Did you know that our immune system (the same cells in our bodies that fight colds and the flu) fights cancer? Scientists recently found this out CTL (Cytotoxic killer T-cell) These cells know what your cells look like. They brush against the cells If they see that the cells outside skin isnt the same as your cells skin

They either eat the cell! Or they tell the cell to die Some cancer cells look like foreign cells (bacteria, etc.) even though they are our own cells!

Remember the recent E.Coli

outbreak in Europe? Scientists have recently found 2 things: 1) Reusable grocery bags can be good and bad. 2) Sometimes washing the outside of a fruit/vegetable isnt good enough (E.Coli were found to also live inside!) E. Coli research in BME that we work on E.Coli Adapted from the Wikimedia Commons file " EscherichiaColi_NIAID.jpg

http://en.wikipedia.org/wiki/File:EscherichiaColi_NIAID.jpg Some last important things 1) Seriously, ask questions/get my help if you need it/you dont completely understand 2) Ill go over topics like my research in more detail as the year goes along. 3) Im really looking forward to having fun this year!
