On The Construction And Interpretation Of Fitness Landscapes For Hiv: A Computational Perspective, Elizabeth Grace Johnson

Doctoral Dissertations

To identify vulnerable viral targets to incorporate into an immunogen, fitness landscapes for the viral proteome have been constructed. These landscapes describe the sum or synergistic replicative cost exacted on the virus for any combination of non-synonymous mutations. Here we attempt to assess the robustness of current computational methods for measuring the fitness cost of HIV polymorphisms in these landscapes. We also address in the following chapters assumptions and shortcomings that may underlie current landscape's uneven ability to predict fitness effects.

In the first chapter, I appraise the robustness of current frame-works that derive fitness costs from patient sequence data. …
