About Derrick Allen

đź“– Summary

Associate Principal Scientist @ Sigilon Therapeutics, Inc. Peer Reviewer / Subject Matter Expert - Contract Position @ GEX Inc As a peer reviewer and subject matter expert, reviewed the development of knowledge graphs used to enhance to artificial intelligence of the Mastering Chemistry online program. Part of this review is the assurance that problems were associated with the correct topic in each chapter. The more involved aspect is the knowledge graph prerequisites for each topic. Review of the developer's suggested prerequisite topics for a specific section were evaluated the appropriateness and strength of that topic as it related to the problem sets present in that section. From June 2014 to January 2018 (3 years 8 months) Atkinson, NHSubject Matter Expert - Contract Position @ GEX Inc Subject matter expert in the field of chemistry, edited and reviewed the solutions manual for Brown's Australian 3rd Edition "Chemistry - The Central Science." This included editing grammar, spelling, and units consistent with Australian English. In many cases, authoring new solutions for new problem sets in the edition was requiredI was originally assigned half of the chapters to edit and review. However, after finishing my portion of the project ahead of schedule, I took on additional chapters to review, edit, and author to insure the project's timely completion. From July 2013 to August 2013 (2 months) Atkinson, NHToxicologist 1 @ Miami-Dade County Part of the screening section of the Miami-Dade Medical Examiner's Office Toxicology Lab. Analyzed biological case samples for drugs of abuse and volatiles for three types of batch samples. The first was a screening and quantitative method for the analysis of alcohols via GC-headspace paired with a flame ionization detector (FID). The second was an ELISA blood drug screen on DMX instrumentation using Neogen ELISA ktis. The third was a urine drug screen broken into three parts: an EMIT assay, salicylate spot test, and liquid liquid extraction and GC/MS analysis. All methods required rigorous quality control and assurance practices that are comparable to GMP, GLP, and GDP practices in the biotechnology and pharmaceutical industry. When case work was light, time was spent validating the lab's blood GHB quantitative method via GC/MS analysis and developing a backup method for the volatile screen and quantitative method in case of instrument downtime. More custodial duties included sample documentation into the lab's laboratory inventory management system (LIMS), preparing buffers, solutions, and tissue homogenates, disposing of medications, and generating reports based on batch results. From June 2012 to February 2013 (9 months) Medical Examiner's OfficeToxicology Intern @ Onondaga County As a third year intern, I was charged with the development of a quantitative method for the analysis of buprenorphine and norbuprenorphine in blood on an underutilized HPLC/MS instrument. Utilizing reverse phase HPLC techniques, I was able to separate the two analytes with efficient resolution within the time restraints given by the chief toxicologist. Solid phase extraction was performed on spiked samples of bovine blood to determine any matrix effects on the analytes. Finally, the parameters of the mass spectrometer were fine tuned for an optimal ion identification profile. A second project was started during this internship for a qualitative method on the same instrument for the methadone derivative, EDDP. While my internship agreement ended before significant progress could be made regarding this method, I communicated my experimental findings to the research associates in the lab and specified a clear direction the method development should take. From January 2011 to May 2011 (5 months) Syracuse, New York AreaTrace Evidence Intern @ Onondaga County Based on the techniques used and presented by the Federal Bureau of Investigation, I developed a method for the analysis of pressure sensitive adhesive packaging tapes in the trace evidence lab. One component of the method was a distinction between the adhesive and film backing components analyzed through micro-FTIR with a diamond crystal. Further analysis was done utilizing polarized light microscopy and the effects of the manufacturing process of the polypropylene tape backing. Testing resolved around limited destructive analysis for the preservation of case samples. Based on results from these methods, I worked closely with the trace evidence supervisor to author the lab's official protocol. From January 2010 to May 2010 (5 months) Syracuse, New York AreaFSC 444/644 Teaching Assistant @ Syracuse University While a graduate student, I was also a teaching assistant for FSC 444/644: Forensic Chemical Analysis. I ran the lab component for a duel graduate/undergraduate class at Syracuse University with four graduate and nine undergraduate students. This included preparing reagents, exemplar samples, running student samples through the lab's GC/MS, and grading student lab reports. I also ran weekly and monthly maintenance on the lab's GC/MS including baking the column and cleaning the ion source. In the lecture component of the course, I ran review sessions and proctored course exams for students. In the absence of the course professor, I taught lectures on the applications of infrared spectroscopy including FTIR and FTIR-ATR and color spot test in forensic analysis. From January 2010 to May 2010 (5 months) Syracuse, New York AreaChemistry Teacher @ Central Catholic High School As a first year high school teacher, I had five classes of approximately twenty students each, the majority of who were high school sophomores. Each class met once a day and had a weekly lab period. By presenting topics in a clear manner, utilizing analogies and an array of problem solving skills, I taught students general chemistry concepts at the college prep level. I made myself available both before and after school for those who had difficulty with the daily lessons or simply those that wanted to practice their skills for better understanding. During lab, safety was a high priority as was the benefit on learning through experimentation. I was offered an extension on my contract for the following school year. I unfortunately had to turn down this offer as I was returning to Syracuse University to pursue an advanced degree in forensic science. From August 2008 to June 2009 (11 months) Lawrence, MassachusettsTrace Evidence Intern @ Onondaga County Based on the techniques used and presented by the Federal Bureau of Investigation, I developed a method for the analysis of spray paints in the trace evidence lab. One component of the method was a distinction between the spectrophotometric properties of the paint analyzed through microspectrophotometry, specifically the reflectance spectra. Class analysis was done utilizing microchemical and microsolutbility testing. Testing resolved around limited destructive analysis for the preservation of case samples. Based on results from these methods, I worked closely with the trace evidence supervisor to author the lab's official protocol. From June 2007 to August 2007 (3 months) Syracuse, New York AreaResearch Scientist II @ Nitto Denko Avecia Inc. Project lead on new client oligonucleotide API molecule, including monitoring of the intermediate species. Included all client analytical development communication, weekly updates, development, limited qualification, and QC lab transfer of HPLC and UPLC purity methods, and authoring of all related documentation. From September 2018 to February 2019 (6 months) Analytical Chemist 1 @ Nitto Denko Avecia Inc. On an accelerated timeline, developed and qualified a non-denaturing ion exchange HPLC purity method for client's oligonucleotide API molecule with monitoring of specific impurities including weekly updates on development with direction for experiments and final parameters. This was in conjunction with authoring of the method with quality control department limitations in mind and authoring, executing, and documenting the protocol driven qualification of the method for release testing for phase 2/3 clinical trials. After the report was submitted, ahead of schedule, validation discussion and protocol writing commenced. Currently overseeing protocol execution. Presented proposals to senior leadership on lab operations to allow for efficient execution of house keeping tasks with minimal disruption to analysts' lab and client related work loads. Executed and documented three protocol driven IND filing forced degradation studies for client's different API duplex oligonucleotides. Each protocol included monitoring of ten different stressors and analysis of two methods for each molecule. Reports were submitted ahead of schedule. Executions resulted in department presentation on the efficient execution and high-throughput processing of protocol execution. Under the supervision of department senior chemist, developed non-denaturing ion exchange and denaturing ion-pairing reverse phase purity methods for client duplex molecule. Development led to limited qualification for phase appropriate material.Authored qualification documentation and participated in the installation of analytical development and quality control instrumentation for client specific methods including Agilent HPLCs and Thermo Integrion IC and CAD detector. From June 2016 to September 2018 (2 years 4 months) Marlborough, MAAnalytical Development Scientist II @ Pharmalucence Part of the QC-Methods and now Analytical Development group at Pharmalucence, a Sun Pharma Company. Chief duty was the development, validation, and transfer of analytical methods for raw material, related substances, and final product vials for both company "legacy" products and contracted products from outside labs. Instrument use primarily focused on HPLC with a diode array detector (DAD) but expanded to cover a charged aerosol detector (CAD) utilizing Agilent ChemStation and OpenLab software. All work was in compliance with FDA and ICH guidelines and cGMP, GMP, GDP, and GLP practices.Subject matter expert in optical particle sizing techniques. Primarily focused on single-particle optical sensing using an AccuSizer 780AD but accompanies methods focused on light microscopy. In conjunction with lab work, authored and revised technical reports, protocols, standard operating procedures, and methods. Included review of colleagues' reports for data accuracy, comprehension, consistency, and conciseness. Upon the resignation of the Associate Director, became the project lead for the single contract product for the company. The added responsibility included not only the transfer of four remaining methods but work with Quality Assurance and Quality Control groups to qualify the remaining instruments, authoring and reviewing transfer protocols and close out reports, and heading biweekly teleconferences between the analytical sub-team and the contract lab. Briefly took on the development of heavy metal testing for raw material and final products utilizing an Agilent 7700 ICP-MS as the company moves away from wet chemical and atomic absorption testing for metals and heads towards compliance with USP/ICH guidelines set for 2018. From August 2014 to June 2016 (1 year 11 months) Billerica MA
