Academic and Research Career

Graduate Studies and Thesis

Christina Birch enrolled at the Massachusetts Institute of Technology (MIT) in 2008 to pursue graduate studies in , earning both a and a degree in June 2015. Her doctoral work, conducted in the laboratory of Jacquin C. Niles, focused on developing novel tools to target malaria-infected red blood cells (iRBCs), a critical factor in the pathogenesis of , which causes over 500,000 deaths annually, predominantly among children in . Birch's PhD thesis, titled Identification of Malaria Parasite-Infected Red Blood Cell Aptamers by Inertial Microfluidics SELEX, introduced an innovative method known as inertial microfluidics SELEX (I-SELEX) to isolate high-affinity aptamers—short, single-stranded DNA or RNA molecules that bind specific targets with precision comparable to antibodies. The methodology leveraged spiral-shaped microfluidic channels to exploit inertial focusing and Dean drag forces, enabling the separation of iRBCs from unbound oligonucleotides through controlled shear and rotational dynamics; this process involved iterative rounds of negative selection against uninfected red blood cells and positive selection on live iRBCs expressing the VAR2CSA protein, which mediates parasite sequestration in the microvasculature. By incorporating biomechanical aspects of iRBC behavior, such as reduced deformability and altered tumbling in fluid flow due to membrane knobs formed by parasite proteins like knob-associated histidine-rich protein (KAHRP), the I-SELEX approach enhanced the efficiency of aptamer enrichment without relying on immobilization or denaturation. This work also led to a patent application (PCT/US2013/043732) for the microfluidics-based aptamer selection method. Key findings from the revealed a diverse panel of aptamers with nanomolar dissociation constants (K_d values ranging from 14 nM to 84 nM), including one that specifically targeted VAR2CSA, a variant surface responsible for placental , and others binding distinct, protease-sensitive epitopes on iRBC surfaces. These aptamers demonstrated high specificity, distinguishing iRBCs from uninfected cells and potentially enabling the mapping of the iRBC surface to uncover novel therapeutic targets. The research highlighted implications for treatment, such as using aptamers to disrupt iRBC adhesion to endothelial cells, thereby mitigating severe complications like cerebral , and facilitating through targeted delivery or as diagnostics for monitoring parasite burden. Birch's thesis work culminated in a seminal publication in Scientific Reports, detailing the I-SELEX method and aptamer characterization, which has since been cited in studies on aptamer-based interventions for parasitic diseases. The full thesis is archived in MIT's DSpace repository. Throughout her graduate studies, Birch faced challenges in balancing her demanding research with emerging commitments to competitive cycling, which she began with the MIT cycling team to counter the isolating nature of solo lab work; she described this equilibrium as essential yet not always easy, providing both social support and physical discipline amid long hours of experimentation.
