Endocrinologists provide treatment for a wide range of functions and disorders of the human body — diabetes, thyroid disorders, infertility, metabolism, glandular cancers, growth hormone deficiency, genetic dysfunction, heart disease, osteoporosis, obesity and hormonal imbalances. Endocrinologists also conduct clinical research.

Physiologists conduct research, improve or develop concepts, theories and methods of operation, and apply scientific knowledge in relation to anatomy; studying and conducting experiments on the forms, structures and other anatomical features of living organisms; and to study and conduct experiments in relation to the effects of medication and other substances on human tissues, organs and processes, and to improve existing medicines or to create new drugs.

Physiologist, Endocrinology conduct research, improve or develop concepts, theories and operational methods, and apply scientific knowledge relating to anatomy, biochemistry, biophysics, physiology, pathology or pharmacology in such fields as medicine, agriculture or industry.

Physiologist, Epidemiology conduct research, improve or develop concepts, theories and methods of operation, and apply scientific knowledge in relation to anatomy; studying and conducting experiments on the forms, structures and other anatomical features of living organisms; and involved in research or applied work that investigates the physiological mechanisms underlying health outcomes in population

Physiologist, Animal conduct research, improve or develop concepts, theories and methods of operation, and apply scientific knowledge in relation to animal anatomy; studying and conducting experiments on the forms, structures and other anatomical features of living organisms; and to study and conduct experiments in relation to the effects of medication and other substances on animals tissues, organs and processes, and to improve existing medicines or to create new drugs.

Physiologist, Neurology conduct research, improve or develop concepts, theories and methods of operation, and apply scientific knowledge in relation to anatomy; studying and conducting experiments on the forms, structures and other anatomical features of living organisms; and who studies the functioning of the nervous system and its impact on various physiological processes. This role often involves conducting research, clinical studies, and experiments to understand the mechanisms underlying neurological functions and disorders.

Physiologist, Plant conduct research, improve or develop concepts, theories and methods of operation, and apply scientific knowledge in relation to plant anatomy; studying and conducting experiments on the forms, structures and other anatomical features of living organisms; and specializes in the study of plant functions and their physiological processes. This field encompasses a wide range of research topics related to how plants grow, develop, respond to their environment, and interact with other organisms.

Pharmacologists study the manner in which drugs and medicaments interact with organisms, living systems, and their parts (i.e. cells, tissues, or organs). Their research aims at identifying substances that can be ingested by humans and that exert adequate biochemical functions for curing illnesses.

Pharmacologist, Toxicology investigate and analyse drugs, chemicals and other substances andresponsible to analytical and scientific techniques to identify toxins such as chemicals, biological substances and radiation, and to assess the potential risks and harmful effects posed by them.

Pharmacologist, Veterinary investigate and analyse drugs, chemicals and other substances, also focuses on the study of how drugs interact with animals, including their mechanisms of action, therapeutic effects, and potential side effects

Toxicologist study the effects that chemical substances or biological and physical agents have in living organisms, more specifically, on the environment and on the animal and human health. They determine doses of the exposure to substances for arising toxic effects in environments, people, and living organisms, and also perform experiments on animals and cell cultures.

Histopathologist studies human or animal tissue to provide data to delineate cause and progress of disease that impairs body function: trains and oversees laboratory personnel in preparing tissue sections or prepares tissue sections from surgical and diagnostic cases and autopsies.

Neuropathologist conduct research, improve or study of disease of nervous system tissue, usually in the form of either small surgical biopsies or whole-body autopsies. neuropathology is a subspecialty of anatomic pathology, neurology, and neurosurgery.

Pathologist is a specialist physicians that undertake research and testing of medical specimens for the diagnosis and treatment of disease. They assist medical practitioners in diagnosing their patients' illness and developing treatment plans.

Pathologist, Forensic performing autopsies on the bodies of people who have died in suspicious circumstances – such as suicide, suspected homicides or deaths in custody.

Pathologist, Animal work in animal disease surveillance, prevention, diagnosis and treatment. They investigate disease (in humans and animals), conduct research and develop medicines. They play a key role in the development of safe and effective medicines, agrochemicals and chemicals, and contribute to animal conservation and protection.

Pathologist, Histopathology is a specialist physicians that undertake research and testing of medical specimens for the diagnosis and treatment of disease. They assist medical practitioners in diagnosing their patients' illness and developing treatment plans.

Pathologist, Clinical is a specialist physicians that undertake research and testing of medical specimens for the diagnosis and treatment of disease. They assist medical practitioners in diagnosing their patients' illness and developing treatment plans.

Pathologist, Neuropathology is a specialist physicians that undertake research and testing of medical specimens for the diagnosis and treatment of disease. They assist medical practitioners in diagnosing their patients' illness and developing treatment plans.

Pathologist, Surgical is a specialist physicians that undertake research and testing of medical specimens for the diagnosis and treatment of disease. They assist medical practitioners in diagnosing their patients' illness and developing treatment plans.
