Please excuse the state of this website at the moment. I am currently building it. I am not Albert Einstein and these are not my publications or posts.

I am a Ph.D. Student in Biostatistics at the University of Pennsylvania with research interests in causal inference, imaging statistics, and semiparametric theory. I hope that these broad interests will facilitate numerous and diverse collaborations in the biomedical and public health fields. My long-term career goal is to continue working in academia as a professor with an added focus in pedagogical techniques for statistics education, particularly for undergraduate students.

I recently finished my undergraduate studies at Amherst College, where I received my B.A. in Mathematics and Music and was inducted into Phi Beta Kappa. Go mammoths!

Can Quantum-Mechanical Description of Physical Reality Be Considered Complete?

In a complete theory there is an element corresponding to each element of reality. A sufficient condition for the reality of a physical quantity is the possibility of predicting it with certainty, without disturbing the system. In quantum mechanics in the case of two physical quantities described by non-commuting operators, the knowledge of one precludes the knowledge of the other. Then either (1) the description of reality given by the wave function in quantum mechanics is not complete or (2) these two quantities cannot have simultaneous reality. Consideration of the problem of making predictions concerning a system on the basis of measurements made on another system that had previously interacted with it leads to the result that if (1) is false then (2) is also false. One is thus led to conclude that the description of reality as given by a wave function is not complete.
