Registration Calendar (important dates for registration, S/U, graduation, etc.)


"This was a lofty chamber, lined and littered with countless bottles. Broad, low tables were scattered about, which bristled with retorts, test-tubes, and little Bunsen lamps, with their blue flickering flames. There was only one student in the room, who was bending over a distant table absorbed in his work. At the sound of our steps he glanced round and sprang to his feet with a cry of pleasure. 'I've found it! I've found it,' he shouted to my companion, running towards us with a test-tube in his hand. 'I have found a re-agent which is precipitated by hemoglobin, and by nothing else.' Had he discovered a gold mine, greater delight could not have shone upon his features. 'Dr. Watson, Mr. Sherlock Holmes,' said Stamford, introducing us."

- Sir Arthur Conan Doyle, A Study in Scarlet, 1887

Course Goals:

Forensic Science plays a critical role in our society and public intrigue has certainly increased with the popularity of several recent television shows. You will see that Forensic Science is a broad, interdisciplinary subject. In its broadest context, forensic science can be thought of as the application of scientific principles to all matters of the law. This can include criminal or civil procedures. In this course, we will be concerned with criminal justice aspects. However, even in this context, consider the scope..biochemical applications to bloodstain analysis or the examination of other body fluids. Knowledge of biology would be required for the examination of human tissues, physiological fluids, pollen, and leaves. Physics is often used in crime scene reconstruction..velocity analysis and metrology to determine the amount and/or direction of force. Materials science is needed during the examination of concrete, paint, glass, dyes, and ceramics. Anthropology relates to the examination of bone, teeth, bite marks, and hair. Mathematics, statistics and probability are important when considering the frequency of occurrence of artifacts and distribution patterns. Geology and microscopy are other important disciplines used in the forensic sciences.

"Forensic Chemistry" would then be the application of chemistry and chemical principles to matters of the law. So, what is "forensic analytical chemistry"? Many view it as "applied analytical chemistry", but that's probably an oversimplification. While forensic chemistry and analytical chemistry share much in common and consider similar questions, such as: "what and/or how much of a given item is in a given sample?", there are differences. For example, forensic chemists often would like to know what the sample originally was, where it came from, and how it got from one place to another. The analytical chemist may be able to determine if a particular liquid is water, but the forensic chemist may want to know if this is lake water, sea water, water used in a particular chemical process, or water resulting from a chemical synthesis. To answer these questions, the tools available to forensic analysts are often the tools found in analytical labs. The purpose of this course is then to examine the analytical methods of analysis used in forensic lab work. The course will introduce and educate you to the types of samples often encountered in forensic work, and the many types of instruments and techniques available for chemical analysis and the type(s) of information these instruments provide. It is my hope that you will then expand your knowledge of the types of analyses and instruments you come into contact with during your scientific career. It is also noted that practitioners in the forensic field often have a solid and high quality scientific background and an education that is multidisciplinary. Other skills that are necessary include the ability to think creatively, exhibit good judgment, and independence.

Winthrop University's faculty adopted a set of four University Level Competencies (ULCs) that describe the qualities our students develop during their Winthrop career.  It is easy to see that this course involves solving problems and developing written communication skills.  However, you will also learn the responsibilities of chemists to the greater good of our planet and society, as well as the global nature of the chemistry enterprise.  Within the discussions of chemical analysis instrument design and applications to forensics, I think you will find this course fits well with all four competencies.

Competency 1:Winthrop graduates think critically and solve problems.
Winthrop University graduates reason logically, evaluate and use evidence, and solve problems. They seek out and assess relevant information from multiple viewpoints to form well-reasoned conclusions. Winthrop graduates consider the full context and consequences of their decisions and continually reexamine their own critical thinking process, including the strengths and weaknesses of their arguments.

Competency 2:Winthrop graduates are personally and socially responsible.
Winthrop University graduates value integrity, perceive moral dimensions, and achieve excellence. They take seriously the perspectives of others, practice ethical reasoning, and reflect on experiences. Winthrop graduates have a sense of responsibility to the broader community and contribute to the greater good.

Competency 3:Winthrop graduates understand the interconnected nature of the world and the time in which they live.
Winthrop University graduates comprehend the historical, social, and global contexts of their disciplines and their lives. They also recognize how their chosen area of study is inextricably linked to other fields. Winthrop graduates collaborate with members of diverse academic, professional, and cultural communities as informed and engaged citizens.

Competency 4:Winthrop graduates communicate effectively.
Winthrop University graduates communicate in a manner appropriate to the subject, occasion, and audience. They create texts - including but not limited to written, oral, and visual presentations - that convey content effectively. Mindful of their voice and the impact of their communication, Winthrop graduates successfully express and exchange ideas.

You are expected to attend each class meeting for the full scheduled time. This is a difficult upper-level course and attendance will help you concentrate on the appropriate material and reinforce the assigned readings and problems. You are required to bring pencil, paper and a scientific calculator to each class. Cell phone calculators are not acceptable.

Students with Disabilities:

Winthrop University is committed to providing access to education.  If you have a condition which may adversely impact your ability to access academics and/or campus life, and you require specific accommodations to complete this course, contact the Office of Accessibility (OA) at 803-323-3290, or,, as early as possible to discuss your concerns.

Additional Requirements for Graduate Level Credit:

Students wishing to receive graduate level credit for this course are required to complete a 5-7 page review paper on a cutting edge analytical technique applied to criminialistics. Resources can be found by reviewing either the "Fundamentals Review" or "Applications Review" issues of the journal, Analytical Chemistry (June 15th issue of even & odd years, respectively). The paper must cite a minimum of 10 primary literature sources and must be submitted by December 6, 2018. Graduate students should be aware that Winthrop's +/- grading system is not applicable to courses taken for graduate credit. Letter grades will be assigned as follows: 92%-100% A; 83%-91% B; 74%-82% C, 55%-73% D.

Syllabus Changes:

While unlikely, the Professor reserves the right to change the course syllabus if circumstances dictate. You will be notified of any change via class meeting time and/or email.

COVID-19 Statement: 
The health and safety of the campus community is Winthrop’s top priority. As socially responsible members of this community, everyone is expected to engage in daily health self-monitoring and to stay home (residence hall or off-campus housing) from on-campus class, work, or activities if they begin experiencing any COVID-related symptoms.  Please do not attend class if you have a fever or any signs of the COVID virus, do not attend class if your roommate or someone you have close contact with acquires the virus, and be respectful of others’ desire to remain COVID-free. Masking on campus remains optional but strongly encouraged, especially in indoor settings around others. Use the Patient Portal COVID-19 form to report illness or exposure and upload the positive test, if relevant.  Students who violate WU guidelines will be asked to comply.  Continued failure to comply may result in referral to the Dean of Students Office as a student conduct violation.

COVID-Related Absence
Students should contact Health Services regarding a positive test, close contact, or enhanced COVID-like symptoms. Any student who has either tested positive, has COVID-like symptoms, or has close contact with someone who has COVID, must contact Health Services. Students should log in to the Patient Portal to complete a C19 form and upload the positive test, if relevant.  Health Services will communicate with the student on what steps to take next, and if need be, the Dean of Students Office will receive absence verification for required isolation and quarantine.  Students who verify their absences through the Dean of Students Office often minimize any academic impact caused by missed class time. Students retain a responsibility to communicate with instructors regarding missed work, and complete assignments in a timely manner as they are able.  Regular communication with faculty is expected so that student progress in the course is not negatively impacted. Health Services will only provide dates of absence, not medical information. Please note, residential students who test positive must follow their personal COVID Quarantine and Isolation Plan.

In person classes generally will not have a remote option; students should not expect to have remote access to the class lecture or discussion, even in the case of absence.
