September xx, xxxx


Associate Professor

University of Pennsylvania

Dear Dr. xxxx

I am applying for the postdoctoral position in your Laboratory. I have done my PhD under the guidance of Dr xxxxx, Director, xxx, xxxx and am presently working as senior research fellow in her laboratory at xxxx. I have submitted my thesis to the university and awaiting Viva-Voice which will be held very soon. I would be immediately available to join your lab.

I am highly motivated to work in the field of T cell activation and differentiation. During the course of my graduate work, I have developed an interest in the inflammation and pathways regulating T cell function. I am especially intrigued by T cell signaling and how different signals TCR, cytokine signaling and co-receptors like xxx and TLR work together to induce T cell proliferation and differentiation. How Notch regulates xxx signal strength by regulating E3-Ubiquitin ligases and thereby modulates T cell differentiation. Kinetics of NF-κB signaling in T cells and role of Notch signalling in the formation of lipid raft and immune synapse are other aspects which excites me.

My graduate work has focused on the immune dysfunction in oral cancer and role of immunosuppressive factors/cells present in the tumor microenvironment. I have worked on the lymphoid as well as myeloid cells during the course of PhD. I have analyzed the different regulators (positive as well as negative) of T cell signaling and how they modulate the T cell function in cancer setting. The important among them was the Notch signaling which has implications in increasing the efficacy of T cell based therapy. We have addressed the root cause of immune dysfunction and its association with MDSCs, Tregs and Th17 cells. We have addressed how MDSCs accumulate, their life span, suppressive potential, and also how they induce Th17 differentiation and inhibit Treg differentiation in in vitro conditions.

Apart from this I have also worked on project “xxxx signaling in regulating effector functions of xxxx cells. I am well versed with the biology and in vitro expansion of xxxxx cells.

During my doctoral program I have thoroughly used multicolor flow cytometry (nine color), western blotting, real-time PCR, siRNA, molecular cloning, co-culture assays, Mixed leukocyte reactions, Immunomagnetic sorting of cells (MDSCs, Tregs, Naïve CD4 cells and CD3 cells, γδ T cells), cytometric bead array and ELISA for quantitation of cytokines, proliferation assay (Dye dilution and tritiated thymidine assay), 51Cr release assay, confocal microscopy, chemotaxis assays to perform the experiments.

I have learned animal handling especially animal dissection, harvesting of liver, spleen, mammary glands, vertebrae and femur bones, Tail vein injection.

I have basic Knowledge about mass spectrometry sample processing; however, I would be highly fascinated to gain expertise in each aspect involved in the project.

 I am interested in the work going on in your laboratory and could be an asset to your Laboratory because of my experience and skill.

I envision my future research to span across some interrelated sub-areas of immune function and dysfunction. I believe that I am an outstanding researcher in my specialty, based on my background and achievements. Having succeeded in the current research, employing the knowledge from different fields of molecular biology and Immunology, I feel well prepared for the further challenging studies and research in the fields of molecular immunology, perhaps on very different topics, as well as on the topics I am familiar with. The main motivation here is to make advances in our understanding of molecular mechanisms of T cell function and its interaction with the tumor.

Enclosed is a copy of my CV and thesis.

I look forward to hearing from you.

Sincerely Yours

Dear Dr. XXX,

I am writing this mail to express my interest in conducting my post-doctoral research under your supervision. I am interested in working on the advertised project of understanding the epigenetic regulation and role of steroid synthesis on physiology and development.

I have also previously worked on the xxx, which is differentially expressed in adult xxx cells during the xxx development and inhibits steroidogenesis by reducing the expression of xxx enzymes. In this study, I proved that the overexpression of xxx in mice testis (mediated by adenovirus) has the potential of inhibiting the differentiation of testicular and prostatic cells by reducing the size of testis and prostate but has no effect on the growth of seminal vesicles. It has also found to reduce the level of xxx and xxx by reducing the steroidogenic enzymes such as xxx, xxx and xxxx. This is the first study reporting a time-course analysis of the implications of long term overexpression of xxx in mice testis and its effect on other organs such as prostate and seminal vesicles. This study suggested that xxxx may play an important role in the differentiation of male reproductive organs such as testis and prostate.

I would further like to extrapolate my substantial experience and research more in this field by analysing the transcription circuitry of steroid biosynthesis at single xxx cell level and thereby on its application in prostate cancer biology.

I have completed Ph.D in xxx (xxx) from Department of xxx, xxxx University. My thesis project entiled as “xxxxxxxxxx”.  The research concentrated upon exploring the role of xxx, a xxxxx-anchored adhesion protein in pathogenicity of xxxxx, a causative agent of xxxx using interdisciplinary approach of molecular biology, cell biology and biochemistry.  Through my doctoral study, I have proposed a model of how the xxxx protein matures in the xxxx lumen upon xxxx anchor attachment. I have then further explore this adhesion protein and the linked signaling pathways in xxxx and published several papers related to this work.

My avid interest and motivation towards research has kept enforcing me to work along while pursuing my jobI worked on varied project like xxxxxxx and some more in association with Dr. xxxxx, professor at xxxx University.

I have conducted immunization based studies on mouse animal model such as Sprague Dawley rats and FVB mice  that involves mice handling, xxxx extraction, purification of Primary Leydig Cells, Preparation of Recombinant Adenovirus, Adenovirus injection, immunohistochemistry, FACS (Fluorescence activated cell sorting), Radioimmunoassay, Western blot analysis, ELISA, Chromatin Immunoprecipitation (ChIP) Assays, neutralization assay, agglutination, immunofluorescence along with using molecular biology approach i.e.  molecular cloning, PCR and expression analysis at both transcript and protein level, mutational studies by side-directed mutagenesis approach and biophysical tools like MALDI-TOF/TOF analysis, Mass SpectrometryIdentification of Proteins, Circular Dichroism (CD), Transmission electron Microscopy (TEM) and data analysis using bioinformatics approach like 2D-Progenesis Samespot Software, functional analyses and  pathways generation using  Ingenuity Pathways Analysis and toppgene suite, PCA analysis alongwith R-programming package “FactoMineR” to reduce the complexity of the dataset, Modelling and Docking Studies using Rosetta 3.2 biomolecular comparative modelling and docking suite, Expasy server, EBI server, CHIMERA software, Multiple alignments, similarity searches, BLAST, Microbial BLAST , FASTA, ClustalW version 1.8, ClustalX 1.8, primer designing.

I believe that these features of knowledge on steroid synthesis, in vivo studies on mice models using interdisciplinary approach, a substantial research experience, skills command over the molecular, cell biology and biochemistry subjects and professional experience in training students along with the strong motivation will go a long way in pursuing the post-doctoral research in your prestigious institute under your guidance. I feel well prepared for the further challenging studies and research to epigenetic regulation of steroid synthesis in leydig cells and its role in development. Given the opportunity, I am confident that I will be able to contribute successfully to this project with the motivation, commitment and determination with hands on experience in this field to succeed in this area. 

Please find enclosed the attached Curriculum Vitae (CV) including the references details. Do suggest if any other information is required from my side.

I look forward to hearing from you.

Thanking You,

Yours sincerely

Dear Dr. xxxx,

With great confidence and enthusiasm I would like to submit my CV for the position of a postdoctoral researcher in your lab. I have obtained my Ph.D. degree in xxx from xxx University, India; I have worked in the lab of Dr. xxx based at xxxx, xxxx. My PhD dissertation focussed on understanding the shape-function relationship of multidomain protein xxxx as a function of temperature using SAXS as a major technique. Currently, I am looking for positions where my skills sets can be put to use in overcoming new and exciting challenges.

It has been a long standing research interest to exploit the tools of biophysics to explore newer possibilities and better drugs for efficacious treatment regimes as well as diagnostic methods; this reason has motivated me to apply for this position in your lab. During my Ph.D. dissertation I got a chance to explore the therapeutically important protein – xxx, a multidomain xxx sensitive protein from a perspective of temperature. The SAXS data analysis showed that the protein remains semi-active at physicological temperatures thereby enabling activation of protein even at semi-optimal concentrations. This data has been published in the journal xxx (xxx). Another part of my study revolved around a truncated yet active version of xxx, here SAXS data coupled with TEM and FPLC helped us to discover temperature induced amyloid formation in native xxx. These amyloids were capable of releasing active protein over prolonged incubation, this was particularly important observation as this could exploited for shipping of therapeutic protein at ambient temperature as well as a sustained release mechanism of treatment. This study was also published in the journal xxx (xxx). Apart from my dissertation project I was involved in numerous other projects in lab.

In addition to my scientific writing I also have experience in preparing and delivering presentations and reports for funding agency as well as key opinion leaders. Apart from my bench work I was extensively involved in other lab duties such as purchasing of lab reagents and maintaining the in house SAXS facility by scheduling and maintaining the records of beamtime allotment. I could accomplish all this due to my high work ethics combined with my targeted approach and interpersonal skills. Post Ph.D. I have briefly worked as Research Associate in lab of Dr. xxx, where my role was to perform field trials of the DNA aptamer based xxx estimation kit developed in the lab. Currently, I am looking for a challenging role and be a part of the team where my technical as well as soft skills can be implemented to contribute constructively in ongoing as well as future projects. I am confident that if I join your lab then my vast experience in SAXS data collection and analysis shall be extremely useful in exploring structural-function relationship of proteins and use this data to develop novel drugs. My particular interest would be high throughput screening of small molecules using SAXS data as well as exploring the possibilities of drug repurposing in cancer targets.

I have enclosed a copy of my CV for your better understanding of my skills and qualifications. I shall more than welcome the opportunity to be interviewed or discuss my experience with you. I may be contacted on +91 xxx or [email protected] Thank you for your time and consideration. Looking forward to hear from you
