Are you research/grad school material?
4
What is research?
5
The two faces of research
6
Finding your Path
  • Talk to people/faculty/students
  • Read about work/research areas
  • Get involved in research
  • Find a MENTOR!
  • In grad school, select a good advisor
  • Go with your passion!

My own passions?
  • Fluid Mechanics and Heat Transfer
  • Teaching

Fluid Mechanics

Fluid Mechanics and Heat Transfer
  • Living organisms are constantly interacting with
    fluids, both internally and externally
  • Blood flows through their circulatory systems,
    oxygen through their lungs/gills, liquids through
    their gastrovascular cavities
  • These fluid flows play a significant role in
    determining the rates of heat, work, and mass
    exchange between the organism and its
    surroundings or within different components of
    the organism itself.

12
So, what about lizards?
  • It is common knowledge that cold-blooded
    vertebrates such as lizards and crocodiles, must
    spend long hours basking in the sun in order to
    maintain an acceptable core body temperature.
  • As ecothermic creatures, they cannot efficiently
    metabolize food to produce their own body heat
    and must instead rely on passive external sources
    of heat such as the sun.

13
Lizard Thermoregulation
  • These lizards modulate their heart rate in order
    to control the heat transfer between their body
    and their surroundings
  • Cool lizards will significantly increase their
    heart rate while lying in the sun warming, but
    will then decrease their heart rate when in a
    cool environment

14
Lizard Thermoregulation II
  • This thermoregulation process based on modulating
    blood flow frequency ensures that the lizards
    remain warm for longer periods during the day by
    increasing their rate of heat transfer with their
    surroundings in the morning and decreasing it in
    the evening

15
First Lizards, Now Dogs???
  • This use of flow pulsation to control heat
    transfer rates is not unique to reptiles
  • The frequency and amplitude of dog panting varies
    with the body temperature of the canine

16
So, what do lizards tell us?
  • Possibility of heat transfer enhancement through
    flow modulation
  • Stay tuned..
