When Kelly Ng 男女操逼视频软件26, a biology major from Perth, Australia, joined the Provost男女操逼视频软件檚 Student-Faculty Undergraduate Research and Creative Inquiry program, she was looking to grow as a scientist and dive deeper into the kind of hands-on, curiosity-driven work that goes far beyond the walls of the classroom.

男女操逼视频软件淚 applied because it offered me an opportunity to grow my skills as a researcher through its provided resources and academic community,男女操逼视频软件 she explained. 男女操逼视频软件淚 was interested in joining a network of students and faculty engaged in independent research, where I could learn from others男女操逼视频软件 experiences in research while developing my own.男女操逼视频软件

With the mentorship of David Boerma, PhD, assistant professor of Biology at Pace and a Research Associate at the American Museum of Natural History, Kelly found herself working on a deceptively simple question: how do bones evolve to meet the needs of how we move? It男女操逼视频软件檚 a question that spans biology, anatomy, biomechanics男女操逼视频软件攁nd in this case, flight.

Together, they are investigating limb structure in the Egyptian fruit bat, a large mammal with a 20+ inch wingspan whose anatomy offers a unique counterpoint to humans. While humans rely on repetitive use of our legs to walk and run, bats rely on their forelimbs (wings) for flight男女操逼视频软件攁 repetitive motion in a different part of the body. Do bats show the same pattern of limb function and bone structure that humans do, just flipped?

We男女操逼视频软件檙e studying Egyptian fruit bats to see if this pattern is the same in bats but for the opposite limbs.男女操逼视频软件

男女操逼视频软件淚f a certain kind of animal has evolved to move a certain part of its skeleton in the same way, over and over again throughout its life (e.g., how your legs move to walk), then because those bones experience repetitive forces, they should end up having extremely consistent shapes across all the individuals of that kind of animal,男女操逼视频软件 Professor Boerma explained. 男女操逼视频软件淲e男女操逼视频软件檙e asking, 男女操逼视频软件榯his idea sounds logical, but is it really true?男女操逼视频软件櫮信俦剖悠等砑䴘

男女操逼视频软件淏eing able to see and segment the structures myself made it easier to grasp how limb shape relates to movement,男女操逼视频软件 Kelly said. 男女操逼视频软件淚t helped me understand those concepts more clearly than I could through lectures or textbooks alone.男女操逼视频软件

For Kelly, the work has been both technical and transformative. A typical day includes loading CT scans of bat specimens into 3D Slicer software, carefully segmenting bones like the femur, tibia, and pelvis, and cleaning digital models to prepare them for analysis. While the learning curve was steep男女操逼视频软件斈信俦剖悠等砑䴗the process of segmenting my first bat took a lot of troubleshooting,男女操逼视频软件 she recalled男女操逼视频软件攖he experience pushed her technical skills and built confidence.

For Boerma, mentoring students like Kelly is one of the most meaningful parts of his work.

He speaks of Kelly男女操逼视频软件檚 early commitment to the project with awe:

男女操逼视频软件淚 gave her a 60-page master男女操逼视频软件檚 thesis from one of our collaborators to read男女操逼视频软件nd she could talk about it with me like a collaborator herself, all before even beginning the project. I can男女操逼视频软件檛 find the words to express to you how much fun that kind of interaction with a student is for a professor.男女操逼视频软件

Beyond bats, biomechanics, or bone variation, this kind of faculty-student partnership is what the Provost男女操逼视频软件檚 program is all about. 男女操逼视频软件淎sking for help is an important part of research,男女操逼视频软件 Kelly said. 男女操逼视频软件淏eing open and honest about what you don男女操逼视频软件檛 know does not mean you男女操逼视频软件檙e less capable男女操逼视频软件攊t男女操逼视频软件檚 an important step in the learning process.男女操逼视频软件

As their research moves into the analysis phase男女操逼视频软件攑otentially laying the groundwork for medical insights into human injury risk or the evolution of vertebrate anatomy男女操逼视频软件擝oerma sees something more fundamental taking shape.

男女操逼视频软件淜elly is growing into the kind of student whose work is now more than just a synthesis of what she reads in a textbook; it男女操逼视频软件檚 the kind of thing that could become part of a textbook in the future.男女操逼视频软件
