Combined MSE and PTFEFrom TODAY to TOMORROW

TODAY: 54 faculty with 6 open positions including the Hightower Chair generating indirect dollars equal to our State budget - weChair, generating indirect dollars equal to our State budget we are a significant profit center to GT and growing.

TOMORROW’s success will be dictated by investments in TOMORROW s success will be dictated by investments in infrastructure at par with the size of our combined program.

Needs include:

Campus-wide state-of-the-art materials characterization user facility New hires research labs Labs for MSE2001 – 2,000 students/yr 40 TAs for the 2001 labs

A strategic investment will produce the number 1 ranked MSE program in the nation ready to leadranked MSE program in the nation ready to lead interdisciplinary research to 2035 and beyond.
