Zaida G. Ramirez Ortiz (class of 2020/21)

Assistant Professor, Department of Medicine at the University of Massachusetts Medical School

I study Immunology with a focus on autoimmune diseases. 1.5 million Americans and 5 million people worldwide suffer with a form of lupus. Approximately, 70% of lupus cases progress to systemic disease referred to as systemic lupus erythematosus (SLE). There is no known cause or cure for lupus, but several studies have shown that patients with SLE have increased levels of circulating ACs, indicating a failure in the clearance of dying cells. Therefore, efficient detection and clearance of apoptotic cells (ACs), a process termed efferocytosis, is critical for control of tissue homeostasis and the resolution of inflammation.  Our current lack of understanding about how phagocytes mediate capture and engulfment of ACs and the signaling pathways initiated by apoptotic debris to prevent loss of tolerance and autoimmunity remain a critical barrier to progress in the field of understanding autoimmune disease pathogenesis. What motivated me to pursue this area is to understand what cause this break in immune tolerance resulting in autoimmunity. Furthermore, the pressing need exists for the development of more specific and less toxic drugs for the treatment of SLE and other autoimmune diseases given that very few drugs have been approved specifically for patients with lupus in the last 50 years.

When I transitioned to an independent position, I thought I needed to be independent from others but that was far from the truth. You need mentors– people in your corner that will guide you and help you be successful. Being a KS fellow, I found that my fellow colleagues became mentors- especially during this unprecedented pandemic time.

Being part of Keystone Symposia as a fellow you become part of a larger family. Fellows from prior years are there to provide advice and you want to celebrate their good news with them. I hope that I can do the same for future fellows!


David J. Gonzalez (class of 2020/21)

Associate Professor, School of Medicine and Skaggs School of Pharmacy, UC San Diego

The last 100 years of microbiology research have clearly established that symbiotic and pathogenic microbes colonizing humans have the ability to impact health, disease, and drug action (Pharmacology and Pharmacy). A next step in studying the complex interaction between host and microbe is to “directly” define the molecular factors that govern biological function (i.e. proteins, metabolites, posttranslational modifications) and delineate their associated mechanisms of action. Towards this goal, the Gonzalez laboratory utilizes a systems scale to single target approach to study bacterial pathogenesis, host responses to infection, and the human microbiome. At its core, the laboratory develops and applies multiplexing quantitative proteomics tools to simultaneously track thousands of protein dynamics and associated post-translational modifications in an accurate and high throughput fashion. We then interface microbiology techniques to characterize important factors identified during these interactions. When appropriate, translational studies of therapeutic value are undertaken in tissue culture, murine models, and by the analysis of human biospecimens. This information is then used to design novel strategies for the detection or treatment of microbial-driven infectious diseases in humans.


Martín M. Riccomagno (class of 2020/21)

Assistant Professor, Molecular, Cell & Systems Bio, UC Riverside

To form the right connections neurons must navigate long distances, guided by attractive and repulsive signals. These ‘guidance cues’ act like streetlights and street signs, and tell the developing neurons where to go to reach their final destinations. Just like when we are driving our cars, neurons encounter multiple signals along the road. While a number of these neuronal guidance signals have been identified, we still don’t understand how multiple attractive and repulsive cues are interpreted inside the developing neuron. Understanding how these cues are integrated and interpreted inside the cell to trigger a diverse array of developmental events is of critical importance if we are to understand the formation, function and malfunction of the human nervous system. We are investigating how a family of intracellular proteins participates in the establishment of brain circuits. These proteins (Cas family) have the potential to interpret and integrate the multiple signals that neurons receive.


Ramon J. Whitson (class of 2020/21)

Amy L. Brewster (class of 2018)

Associate Professor, Biological Sciences, Southern Methodist University

My general research interests are to study mechanisms that underlie molecular and structural dendritic alterations, seizures, and behavioral deficits in epilepsy. Epilepsy is a neurological disorder characterized by the occurrence of spontaneous recurrent seizures. In addition, epilepsy is highly co-morbid with cognitive and behavioral deficits along with catastrophic consequences such as sudden unexpected death. Unfortunately, anti-epileptic medications do not suppress seizures in one-third of the epileptic population. Therefore, our research goal is to identify potential therapeutic targets for the prevention, treatment, and control of this neurological disorder. Through our scientific discoveries we seek to help stop seizures and improve cognitive outcomes in those affected by severe epilepsy. Our research goal is to identify whether neuro-immune interactions contribute to the construction of hyperexcitable neuronal networks that may promote seizures and cognitive deficits in epilepsy. We seek to determine the role that microglial inflammatory and phagocytic signaling mediated by the classical complement cascade (C1q-C3), Triggering receptors expressed on myeloid cells (Trem2), Colony stimulating factor 1 receptor (CSFR1), and the mechanistic target of Rapamycin (mTOR), play in pathological synaptodendritic remodeling, seizures, and cognitive deficits in experimental models of epilepsy.

Diana M. Cittelly (class of 2015)

Assistant Professor, Breast Cancer Research Pathology, University of Colorado Anschutz Medical Campus

The Cittelly laboratory studies the mechanisms that allow breast cancer cells to metastasize to the brain, with long-term goal of identifying alternative treatment options for women with this -often terminal- diagnosis. Different from lung and bone metastases (which are common sites of breast cancer metastases), brain metastases develop in a unique organ comprised by a very specialized groups of cells that control brain function in a tightly regulated manner. We are interested in defining the mechanisms by which glial cells (reactive astrocytes and microglia) play pro and anti-metastatic roles during brain colonization, defining how hormones alter the neuro inflammatory milieu through metastatic colonization, and how the brain niche contributes to failure of standard of care for brain metastasis (i.e Radiation, targeted therapies).


Alambert~Renata

Renata Pereira Alambert (class of 2015)

Assistant Professor, Internal Medicine, University of Iowa Carver College of Medicine

Diabetes is one of the fastest growing epidemics nationwide, and its complications remain a major public health burden. Insulin resistance is a hallmark of type 2 diabetes and obesity, and elucidating its pathophysiology will be crucial to combat diabetes. Several studies have correlated mitochondrial dysfunction with insulin resistance and diabetes. However, whether impaired mitochondrial function plays a casual role or is secondary to the disease is still incompletely understood. My current research focuses on elucidating the link between the role of mitochondrial fusion and fission (mitochondrial dynamics) on metabolically relevant tissues on the manifestation of insulin resistance. I have recently demonstrated that, by deleting the fusion protein OPA1 from skeletal muscle we induce mitochondrial stress and ER stress, but surprisingly renderer mice resistant to diet-induced obesity and insulin resistance via FGF21 secretion from muscle. My current research projects aim to understand the mechanisms for muscle regulation of FGF21 and the role of OPA1 and mitochondrial dynamics in adipose tissue physiology and in the adaptation to caloric excess.


Vinicio de Jesus Perez (class of 2014)

Associate Professor of Medicine, Stanford University Medical Center

Our lab focuses on understanding the genetic, cellular and molecular mechanisms involved in the pathogenesis of pulmonary arterial hypertension (PAH).  We are interested in understanding how pulmonary arteries respond to injury and identify novel genetic modifiers whose dysfunction can trigger small vessel loss and vascular remodeling in PAH patients.  In particular, we are currently focused on exploring how the Wnt signaling pathways regulate the behavior of pulmonary artery endothelial cells (PAECs), smooth muscle cells (PASMCs) and pericytes in response to injury and whether mutations related to these pathway can affect signaling via other pathways relevant to PAH resulting in development of clinical disease.  The overarching goal of our work is to identify potential biomarkers and drug targets that can be used in the development of novel diagnostic and treatment approaches to offer patients afflicted with this devastating disease.  In recent years, our lab has broadened its research interests to include other rare pulmonary diseases such as idiopathic lung fibrosis and lymphangioleiomyomatosis (LAM).  We are testing novel approaches to prevent and reverse disease progression in animal models of these diseases with the goal of discovering novel therapies to alter the natural course of these life-threatening diseases.


Sharilyn Almodovar (class of 2013)

Assistant Professor, Texas Tech University Health Sciences Center

Throughout the years, Dr. Almodovar has investigated Human Immunodeficiency Virus (HIV) and its involvement in pulmonary vascular diseases like Pulmonary Hypertension. Pulmonary Hypertension (PH) is a long-term complication of HIV infection and is a cause of mortality unrelated to AIDS. What in HIV causes or contributes to PH was –and still remains- largely unknown. As a postdoctoral fellow in Colorado, Dr. Almodovar contributed her experience in molecular virology and bioinformatics to uncover specific HIV Nef polymorphisms associated with the pulmonary hypertensive phenotype in HIV-infected individuals. In addition, her work helped to confirm the utility of SHIVnef-infected macaques as suitable models of HIV-associated pulmonary vascular remodeling, as the pathogenetic changes they observed are concordant with features of several forms of PH including idiopathic, familial, scleroderma-induced, and HIV-associated PH. Her research group then moved on to now investigate the role of CXCR4-utilizing HIV (X4 viruses) in pulmonary hypertension and pulmonary vascular disease, as well as using humanized mice as the next step to continue mechanistic studies here at TTUHSC.


Joaquin N. Lugo (class of 2013)

Associate Professor of Psychology and Neuroscience, Graduate Program Director, Ph.D. Program, Baylor University

I investigate how seizures during different periods of neurodevelopment result in long-term changes in learning and memory, social behavior, and repetitive/stereotyped behaviors. I also investigate the neural mechanisms that mediate these changes through molecular and imaging techniques. In particular, I am examining how seizures induce changes in the mTOR, MAPK, and Canonical Wnt signaling pathways and how these changes lead to alterations in potassium channels and other synaptic proteins.  My interest in examining behavioral changes is also why I am examining the link between autism and epilepsy. Children with epilepsy have a high comorbidity with autism but the underlying mechanism is not known. I plan to investigate how seizures could lead to autistic-like behavior in mice. My third research question is how seizures during early development impact brain growth and bone growth. We use genetic and chemoconvulant models of epilepsy and determine their bone phenotype in adulthood.

Blythe Elena Janowiak (class of 2012)

Associate Professor of Biology, Saint Louis University

The Janowiak lab uses biochemistry, microbiology, and molecular genetics to explore the relationship between microbes and their environment. The lab has two main focuses: 1) Gram-positive pathogenic bacteria and their response to oxidative stresses produced by the mammalian host, and 2) The contribution of glutathione and other antioxidants to the survival and maintenance of bacteria residing in the mouse vaginal microbiome. Our bacterium of interest is Group B Streptococcus (Streptococcus agalactiae). Our favorite oxidative stress response is glutathione, and we specifically study its synthesis, import, export, and metabolism in the bacteria. To study the regulation of and the molecular mechanisms involved with glutathione metabolism, we are employing a combination of transcriptomics, metabolomics, and good old fashion biochemistry. The lab is examining the effect of glutathione metabolism on the biodiversity of the vaginal microbiota. Group B Streptococcus is often found in the healthy vaginal microbiome, but can become an opportunistic pathogen and cause significant disease. Therefore, the lab is interested in the role antioxidants, namely glutathione, play in maintaining a healthy vaginal microbiome.

Fatima Rivas (class of 2010)

Assistant Professor, Louisiana State University

The Rivas group is interested in developing new chemical tools from natural products to tease out biological processes with the potential of treating human disease. Natural products chemistry is the study of substances produced by living organisms. We investigate them to improve our understanding of biological processes and identify compounds that may lead to the development of new therapeutic agents. We also develop derivatization strategies to discover new chemical matter. We used a variety of methods, such as bio-guided isolation, reactivity-guided labeling, and total syntheses, which provide access to novel natural products based on their bioactivity or reactivity. These approaches have the potential to uncover fascinating new chemical structures with profound insight into the vast chemical space of natural products and their capability to bring healing to human disease. One of our discoveries, the synthesis and biological evaluation of colletoic acid, a remarkable selective inhibitor of a metabolic enzyme that promotes adipose dysfunction.  We are now studying ways to identify suitable delivery systems to test this compound and its derivatives in in vivo models.

These research endeavors promise to discover new natural products and identification of novel biological targets to further facilitate the development of the next generation of molecular probes to alleviate human disease.

In the summers she has enjoyed working with undergraduate students as part of NIH-funded programs.  Wherever possible, Fatima has contributed voluntarily to teaching.  She has been active in her communities, serving on NIH panels, organizing symposia at ACS meetings and participating in formal student mentoring programs.
