Well, informally, here is why I consider myself an expert in the “fields of expertise” listed in my profile:
cats: I own three, have domesticated a once fully feral cat to be a loving indoor-only cat, have saved 2 kittens from a dumpster, volunteer working with cats for a local animal-rescue organization, and participate in trap/neuter/return program.
college: I was great at it (Summa Cum Laude!) and was a pro at everything involving college while in undergrad. I also had a part-time job as an SAT tutor, and so I worked with tons of kids on their college applications and helping them choose colleges.
drugs: I’ve done most of these, some for extended periods of time, and have also studied their effects from a scientific perspective.
facebook: I have had facebook for about 5 years and feel well-versed in all of its nuances.
grad school: I was the queen of grad school applications… I applied to 16 schools, interviewed at 14, and was accepted at 12. I just completed my first semester of grad school and feel equipped to answer anyone’s questions regarding grad school applications and grad school politics.
grammar: I have impeccable grammar and spent years tutoring the ACT English and SAT writing (new) sections of those standardized tests.
jobs: I have always been great at scoring awesome jobs during the summer months between college and am able to offer sound advice regarding resumes, interviews, and office politics.
Lost: I am obsessed with this show and follow it to a ridiculous degree. I can answer any question about theories, characters, episodes, etc., and I also read a large amount of Lost fansites.
math: I have a math mind, I have taken many advanced math courses, and I use math in my daily life. I feel I could answer almost any question a Flutherer would have about math.
neuroscience: This is what I currently study, and I spend my days doing research in this field.
psychology: This was my undergrad major, and I am quite knowledgeable about most things psychology.
science: I am girl of science.
television: I watch a lot of this, and I also read a lot about all of my favorite shows. This is my favorite topic of conversation. I love discussing various episodes and characters of any good TV show.
tutoring: I was a standardized test prep and academic tutor for 4 years. I tutored more than 55 students individually and learned more than I ever thought was possible. (Who knew there really were 55 different learning styles?) I was an excellent tutor and tailored my lessons very specifically to each student’s needs. I also taught 4 after-school SAT prep courses.
vision: This is my specialization within neuroscience. I have been researching various aspects of vision since I was a sophomore in undergrad.
Of course, there is always more to learn in any of these fields, and the more I learn about them, the more I realize that. :)
