Biography

Hello, my name is Doreen and I am a recent graduate from the Chemistry PhD program at Stanford University (2020). Currently, I am a Senior Scientist at Medtronic.

My background is broad, as I focused on Materials Engineering during my graduate research studies, engineering chemical properties of materials for interface with biological systems. During this time, I also was a teaching assistant for the course "Organic and Biological Materials," a course assistant for "Separations" course, and a mentor for an undergraduate student in the lab.

Prior to this, I completed my BS in Chemistry at Caltech (2015). Here I TA'ed "Cell Biology Laboratory" and my studies covered a comprehensive program of chemistry, math, and physics.

I am passionate about effective ways of teaching students and educating students in a way that suits them best for their learning style. I have also presented at many conferences and written scientific papers - driving my ability to communicate in a concise and effective manner.

Thanks in advance and look forward to connecting.

General Chemistry: Principles and Modern Applications

A relationship between bond lengths and single covalent radii of atoms is given on page $443 .$ Use this relationship together with appropriate data from Table 10.2 to estimate these single-bond lengths. (a) $\mathrm{I}-\mathrm{Cl} ;$ (b) $\mathrm{O}-\mathrm{Cl} ;$ (c) $\mathrm{C}-\mathrm{F} ;$ (d) $\mathrm{C}-\mathrm{Br}$.
