Astrobiology Areas of Interest: Origin & Evolution of Life on Earth, Life in Extreme Environments
I study the composition and evolution of the Earth and early solar system by using stable isotope systematics measured by multi-collector inductively coupled plasma mass spectrometry (MC-ICPMS). Examples of current projects include:
Formation and differentiation of the Moon, Mars and other extraterrestrial bodies by studying isotopic compositions of lunar samples, Martian meteorites, chondrites and achondrites.
Composition, differentiation and evolution of the bulk Earth/ major reservoirs through studies of isotopic compositions of peridotites, komatiites, basalts, arc lavas, granites and seawater.
Global elemental cycling among hydrosphere, crust and mantle through isotopic studies of river water, sedimentary rocks, weathering profiles, seafloor alteration and metamorphic rocks.
Geothermometry and geospeedometry through studies of equilibrium and kinetic isotope fractionation in igneous & metamorphic minerals, theoretical predications and lab experiments.
Paleoceanography and paleoclimate through isotopic and elemental studies of coral samples, speleothem, loess and lake sediments.
Studies of isotope fractionation during biogenic processes through laboratory experiments and by using natural samples

Sometimes stepping back and looking at where you stand can have a great impact on your approach to things. The same can be said for a Career Plan. I’m detective Frank Money – and I’m the man for understanding Career Plans.
At various stages of your life, having a Career Plan and reviewing that plan can keep you on the right path, helping you achieve a higher salary, job security and a rewarding career – doing what you love.
Ask yourself these questions:
- What is the marketability of the degree you are pursuing?
- Are there steps you might take to add to your potential employability and earning power?
A career plan is simply a step-by-step assessment, finding out the things you need to do, and the order you need to do them in, to get the career you want.For college-aged folks, taking the time to establish a career plan can act as a blueprint for building your career.
1 – Assess yourself, Take time now to learn how your skills, values, interests, and personality might influence your career choices.
2 – Understand the careers available to your career choice. Do you really know what jobs you might qualify for upon graduation?
3 – Participate in your career choice. Set yourself apart from other recent graduates, participate in internships, mentoring programs, and other work-based learning experiences.
4 – Network. Look for career-related student groups, professional associations, or other groups that can help you to network.
Taking the time to organize yourself with a Career Plan will help you take the right steps toward your career future.
April is National Financial Literacy Month, Detective Frank Money’s favorite month! To celebrate the importance of being financially literate, Detective Money is going to post financial literacy tips every day.
