ParaSITE
paraSITE proposes the appropriation of exterior ventilation systems on existing architecture to inflate pneumatic shelters that are designed for homeless people. This project involves the production of a series of inflatable prototypes, the distribution of these devices to a group of homeless …

Immunity to Leishmania mexicana parasite
Background: Cutaneous Leishmaniasis caused by the Leishmania mexicana complex is associated with unpleasant or disfiguring lesions, for which there only limited treatment options. The life cycle of L. mexicana consists of two stages which involve different immune evasion mechanisms: promastigote …

ECOLOGICAL PERSPECTIVES ON HOST-PARASITE COEVOLUTION
… at host immunity loci and corresponding parasite antigenicity loci, maintained by coevolution in pathosystems, is common and can persist for millions of years. Such polymorphisms and how they persist or break down are both fundamentally interesting and important for human health and …

Host-Parasite Interactions Within Food Webs
… employed in nature, yet the effects of parasites are often thought to be minimal, and the vast majority of studies fail to consider parasites and their effects on host organisms. This is likely a problem, as the magnitude of parasite-mediated effects on their hosts can be quite large. …

Cancer cell behaviour following parasite exposure
… about helminths and the effect that these parasites have on cancer progression.

Emerging Infectious Disease: Host and Parasite Perspectives
… and related haematozoa are nearly ubiquitous parasites that can impose fitness costs of variable severity and may, in some cases, cause substantial mortality in their host populations. One example of the latter, the emergence of avian malaria in the endemic avifauna of Hawaii, has become a …

Parasite-host interactions in an arctic goose colony
… effect these may have on their host populations. Parasites influence the reproductive success of their hosts in some cases. Studies on impacts of ectoparasites on avian reproductive success have generally been focused on species with altricial young. I studied the abundance of an apparently newly …

Liver fluke development: a target for parasite control?
… a debilitating disease caused by flatworm parasites belonging to the genus Fasciola, is a prominent threat to global food security due to its widespread infection of agriculturally significant ruminants. Recent studies have identified a population of proliferative cells within Fasciola …

Transcript Diversity In The Protozoan Parasite Toxoplasma Gondii
… data from the obligate intracellular protozoan parasite Toxoplasma gondii, a ubiquitous pathogen of humans and other vertebrates. We produced and sequenced 24 strand-specific RNA libraries from several parasite strains and developmental stages, and examined these in conjunction with 45 …

Contributions to modeling parasite dynamics and dimension reduction
… thesis, I have worked on two projects: modeling parasite dynamics (Chapter 2) and complementary dimensionality analysis (Chapter 3). In the first project, we study a longitudinal data of infection with the parasite Giardia lamblia among children in Kenya. Understanding the infection and recovery …

Drug discovery against malaria parasite: drug repositioning strategy
… the target of bisphosphonate in malaria parasite and, second, inhouse synthesized library of prenyl synthase inhibitors was used to find the lead, an analog of zoledronate, against the parasite, which the x-ray structure bound to target enzyme, farnesyl diphosphate synthase (FPPS), was …

Variable immunity and its consequences for parasite dynamics
… by three common factors: susceptible hosts, parasites, and environmental conditions. Over the past three decades, disease ecology has provided overwhelming evidence that environmental conditions can shape disease risk by altering host-parasite interactions. For example, shifting global …

Characterisation of Plasmodium parasite sexual commitment and development
… year. The disease is caused by a single-celled parasite of the genus Plasmodium, which establishes infection via a bite from an Anopheline mosquito. While the parasite progresses through a complex range of life stages, it is the blood stages, or the intraerythrocytic developmental cycle (IDC), …

Parasite communities of wild turkeys (Meleagris gallopavo) in Colorado
… relatively few studies have addressed their parasites, and specifically the helminth parasites. Island Biogeography Theory has been applied to parasite and host relationships in which the host is considered an island. In particular, the Island Size hypothesis predicts that a larger island …

Interrogating Host-Parasite Dynamics During Plasmodium Liver Stage Infection
… health burden and is caused by the apicomplexan parasite Plasmodium. Plasmodium spp. are transmitted by an Anopheles mosquito and require both host and vector to complete their life cycle. Once in the host, parasites travel to the liver and undergo an obligatory and asymptomatic liver stage. This …

Investigation of Specialized Metabolites in Apicomplexan Parasite Life Cycles
… various ecological niches are apicomplexan parasites. The most notorious parasites belong to the genera Plasmodium and Toxoplasma, which are responsible for malaria and toxoplasmosis, respectively. Traditional efforts to reduce malaria include pharmaceuticals and prevention of mosquito-based …
